Albeit rare, the majority of identified bone lesions in pregnancy spare the pelvis. Once encountered with a pelvic bone lesion in pregnancy, the obstetrician may face a challenging situation as it is difficult to determine and predict the effects that labor and parturition impart on the pelvic bones. Bone changes and pelvic bone fractures have been well documented during childbirth. The data regarding clinical outcomes and management of pregnancies complicated by pelvic ABCs is scant. Highly suspected to represent an aneurysmal bone cyst, the clinical evaluation of a pelvic lesion in the ilium of a pregnant individual is presented, and modes of delivery in such a scenario are discussed.

Introduction Aneurysmal bone cysts (ABCs) are pseudotumoral bone lesions of unknown etiology that are also hypervascularized, benign, and locally destructive. They are rare in the base of the skull. The present case report describes a case of aneurysmal bone cyst in the sella turcica. Case Report The present study was developed at the department of neurosurgery of the Hospital Universitário Professor Alberto Antunes of the Universidade Federal de Alagoas (HUPAA-AL, in the Portuguese acronym), Maceió, state of Alagoas, Brazil, and is accompanied by a review of the literature from the PubMed database. A 17-year-old female patient with bitemporal hemianopia and intense left hemicranial headache associated with symptoms from the cranial nerves contained in the cavernous sinus. Neuroimaging evidenced a large lesion in the suprasellar region with calcification foci, sellar erosion, and extension to the cavernous sinus. The patient was submitted to a partial lesion resection and the histopathological analysis showed an aneurysmal bone cyst. Conclusion A rare case of intracranial aneurysmal bone cyst, with the important differential diagnosis from pituitary adenoma.

Introduction. Aneurysmal bone cyst is a benign bone lesion composed of blood filled cystic cavities lined by fibrous septa. Its malignant transformation of is a rare event. Case report. We report a case of a lesion in the second metatarsal bone in a 29-year-old male, presented as a slight swelling of the right foot. After the curettage had been done, the diagnosis of aneurysmal bone cyst was made but the recurrence occurred 4 years later. The biopsy of the recurrent tumor showed compact neoplastic tissue consistent with diagnosis of giant cell tumor with malignancy. The malignant component was recognized as a high grade sarcoma with osteoid production. A tumor mass with the whole II metatarsal bone was extirpated and a resected part of fibula was transplanted. A year later, another recurrence occurred, an amputation was performed and a teleangiectatic osteosarcoma with ingvinal lymph nodes metastases was diagnosed. No other tumor mass was confirmed, either clinically or by imaging techniques at the time of his third operation. He died 4 months later with multiple pulmonary metastases. Conclusion. We emphasize the importance of team work in order to achieve the accurate diagnosis, highlighting careful radiological examinations, good sampling and awareness of unusual cases in bone tumor pathology.

Abstract Objective: Traumatic retroperitoneal hematoma (RPH) is an underdiagnosed entity, turned to have a high mortality rate, when is not earlier diagnosed. Our aim was to analyze our experiences in patients with traumatic RPH complicated with bone fractures, and highlight the problems in diagnosis and treatment to facilitate the surgeon’s decision. Methods: In this retrospective study, all cases who presented to the emergency room (ER) and/or admitted to our center with bone fractures complicated with RPH from January 2016 to December 2019 were included (4-years data). Data collected included age, hematoma zones, fracture production mechanisms, mortality, surgical intervention, bones lesions frequency, frequency of pelvic bone injuries, complications and biochemical and hematological analysis (e.g. hemoglobin (Hb), hematocrit (Ht), platelets (PLT), leukocytes (Leu), aspartate aminotransferase level (AST), alanine aminotransferase level (ALT) and creatinine (Cr). All RPHs were diagnosed using computed tomography scan. Results: A total number of 173 RPH cases with bone fractures were included with a mean age of 48.80±1.40. Zone II and III (lateral and pelvic hematoma) bleed were the most common type of RPH. The main fracture production mechanism was road accident (n=110). The bone lesions frequency besides pelvis, was seen in lumbar vertebral fractures (e.g. 19 cases in 2016, 38 cases in 2017, 45 in 2018 and 40 in 2019), comparing with the other fractures, without any statistical significance. An important significance was seen for frequency of pelvic bone injuries, when comparing 2016 with 2018 year (p=0.040). Furthermore, the complications seem to have a statistical significance when 2016 year was compared with all the other years (p=0.030, p=0.035, p=0.052). Regarding the biochemical and hematological analysis, a statistical significance was seen at Hb (when 2016 was compared with 2017 year, p=0.007 and 2018 year, p=0.001), Ht (when 2016 was compared with 2017, p=0.054 and 2018, p=0.002), PLT (when 2016 was compared with 2018 year, p=0.0004, and 2019 year, p=0.002) and ALT (when 2016 was compared with 2017 year, p=0.026, and 2018 year, p=0.026). The highest mortality was registered in 2019 (n=11), being statistically significant in comparison with 2016 year (p=0.030). About 109 patients were treated conservatively, and 64 by surgical interventions. Conclusion: There is a lack of evidence for the best management in RPH, conservative approaching being reserved only for patients who are stable. Therefore, traumatic RPH complicated with bone fractures, especially lumbar vertebral fractures, represent a life-threatening condition, early diagnosis and correct treatment is of upmost importance.

Surgical Removal

Aneurysmal bone cyst (ABC) is a non-neoplastic locally destructive primary bone lesion mostly occurring within the first two decades of life with female predominance. Cervical spine ABCs are a very rare clinical entity with particularly demanding surgical resection limited by the involvement of nearby neurovascular structures and a risk for cervical spine instability. We present a case of a 17-year-old patient with a symptomatic ABC of the cervical spine who underwent surgical removal of the osseous lesion with good postoperative outcome. There are different therapeutic strategies for ABC management, but complete surgical removal of the cyst remains one of the most important predictors of favorable outcome, although it can be often limited, especially in the cervical region. Previously described lesions have a very high recurrence rate and therefore different additional methods, such as radiotherapy, embolization and sclerosation have been used in addition to surgical resection. Further studies are necessary for development of evidence-based treatment regimens for cervical spine ABCs in pediatric population.

Aneurysmal bone cyst (ABC) is a benign progressive expansile bone lesion that usually involves often located in vertebrae, long tubular bones and flat bones. A small percentage of aneurysmal bone cysts arise from the skull base. Skull base involvement is very rare. Here, we describe a 22-year young man presented with diplopia, right sided facial paresis and right sided sensori-neural hearing loss. CT scan and MRI showed a right petrous apex skull base mass that was confirmed as ABC in histopathology after surgical removal. Journal of Science Foundation, January 2020;18(1):25-28

Background. Aneurysmal bone cyst (ABC) is a benign, expansive, osteolytic lesion that mainly occurs in young people, and involves the skull bones only exceptionally. The origin of ABC is controversial: secondary reactive bone lesion, or primary disease that represents an independent nosological entity. Blunt head trauma was suggested as a possible etiological factor. Case report. A case of a 19-year old man with primary ABC of the right frontal bone was reported. The lesion was totally excised through frontal craniotomy, and the skull bone defect primarily reconstructed with an acrilate cranioplasty. Five years after the surgery, the patient was without signs of local recurrence. Conclusion. Clinical and neuroradiological presentation of the skull ABC was not specific. Pathohistology confirmed the diagnosis. Total excision was the treatment of choice.

Rare Lesion

An intraosseous lipoma is a rare benign bone lesion that proliferates from mature lipocytes. It occurs most frequently in the lower limb, particularly in the calcaneus. The talus is an unusual location for this rare lesion. A review of the literature produced only two reports with talar intraosseous lipomas under the name of intraosseous lipomatosis, which described multiple lipomas in different areas. We describe a 38-year-old male patient who had an isolated intraosseous lipoma with an osteochondral defect in the talus and was treated with autologous osteochondral graft transplantation by medial malleolar osteotomy. He could walk with full weightbearing without any assistance at the end of 12 months. Intraosseous lipoma localized in the talus may be confused radiologically with other bone lesions, especially with unicameral bone cyst, if it is associated with an osteochondral defect. Autologous osteochondral graft transplantation is a successful treatment method for talar intraosseous lipoma. (J Am Podiatr Med Assoc 101(3): 269–274, 2011)

Adamantinoma, a rare bone lesion of the tibia and fibula, has two distinct variants, classic adamantinoma and osteofibrous dysplasia-like adamantinoma. Composite lesions have not been described. Aneurysmal bone cyst is a benign cystic lesion which may also occur in the tibia and fibula. We report an unusual case of classic adamantinoma with osteofibrous dysplasia-like areas and foci of secondary aneurysmal bone cyst with prominent giant cells. A lesion was diagnosed in a 17-year-old girl with a 14-year history of a slowly enlarging left tibial mass and increasing deformity. Pathologically, the predominant pattern was classic adamantinoma, with minor foci of osteofibrous dysplasia-like adamantinoma and areas of secondary aneurysmal bone cyst with abundant multinucleated giant cells. We report the clinical, radiologic, and pathologic features of this case, and summarize lesions associated with secondary aneurysmal bone cyst. To our knowledge, the association of adamantinoma with secondary aneurysmal bone cyst has not been previously reported.

Paleopathology, summarily defined as the study of past diseases, has on the differential diagnosis a major challenge. Histological techniques offered the possibility to look inside the microstructure of both normal and abnormal body tissues to diagnose diseases that affected past populations, leading to the development of a new field of research - paleohistology or paleohistopathology. However, and contrary to paleopathology whose journey is well-established, in paleohistopathology there are many gaps that need to be filled. This occurrence is probably the result of a nonsystematic and non-standardized approach to the microscopic study of skeletal abnormalities, especially those of infectious origin involving periosteal new bone formation (PNBF). The aims of this work were: (1) to search for differences in the microstructure of PNBF with regard to the cause of death of the individual; (2) to infer differences between the macroscopic and microscopic proprieties of bone lesions, and (3) to ascertain the impact of diagenetic changes in the bone microstructure. For histological examination under transmitted and polarized light, a total of 34 dry bone specimens: 26 belonging to 23 individuals from the Human Identified Skeletal Collection from the Bocage Museum (Lisbon, Portugal), and eight from archaeological skeletons were prepared. The documented bone samples were collected from individuals who died from tuberculosis-TB (Group 1), non-TB infectious diseases (Group 2), and conditions other than those of TB and non-TB infectious origin (Group 3).With regard to the diagnosis of pathological conditions, differences in the microstructure of PNBF were seen between Group 1 and Group 2 of cause of death and within groups. Multiple layers of “appositional bone” enclosing numerous primary vascular canals were the pattern most commonly observed (n=4) in the samples from Group 1. This type of PNBF seems to mimic the appositional growth that characterizes the modeling process of the periosteal and endosteal membranes (PEM) during rapid growth periods. An abnormal stimulation of growth factors, especially of the vascular endothelial growth factor (VEGF) may eventually explain the extensive hypervascularization observed (Fig. 1 A-B). Periosteal lesions on ribs are normally associated with pulmonary infection (e.g. TB) disseminated from the lungs (via pleura) to the ribs. However, three samples (one from Group 1, two from Group 2) presented a microstructure compatible with subperiosteal hematomas (Fig. 1 C-D). Repetitive microtrauma (e.g. chest wall vibration) that causes detachment of the periosteum may have leaded to subperiosteal bleeding and hematoma formation. These observations suggest that beyond pulmonary diseases other mechanisms may stimulate PNBF on the visceral surface of ribs. Histological analysis was also fundamental in the description and characterization of bone changes. For example, of the five samples with “consolidated” fracture callus, only two presented a truly mature and remodeled microstructure. This means that the outer surface of a bone lesion may not give a complete picture of the tissues response (Fig. 2 A-B). In spite of the good preservation of some bone samples, massive diagenetic changes due to the action of bacteria and fungi were observed at microscopic level. This clearly suggests that gross inspection is not a good measure of the bone tissue quality. In contrast, microscopy is essential to differentiate between pseudopathology and physiological or pathological signs.Microscopy revealed surprising results that reinforce the pertinence of applying histological techniques in the description and diagnosis of bone changes in human remains.This research was supported by Fundação para a Ciência e Tecnologia, Portugal [SFRH/BD/36739/2007, Sandra Assis].
