The most common benign tumors of the mesenchyme are the lipomas. Benign fatty tumors can arise in any location in which fat is present. Fibrolipomas are characterised by fat modules. Most patients affected by such tumors are in the fifth or sixth decade of life. When very close to vital structures such as joints, they may cause functional limitations as well as pain. Osseous and chondroid metaplasia can infrequently manifest after chronic persistence. Given the rarity of this condition, a case of a big fibrolipoma of Hoffa’s fat pad with osseous and cartilaginous metaplasia is reported. A 44-year-old woman presented with an enlarging soft mass on the right knee in the infrapatellar fat pad. After a thorough preoperative clinical and imaging examination, the mass was removed and sent to laboratory where the diagnosis was put. One year after surgery, both local and general condition of the patient were good and no signs of recurrence were found.

P Concentration

The aim of the study was to assess phosphorus (P) concentration in structures of the knee joint—including the tibial spongy bone, articular cartilage, meniscus, anterior cruciate ligament, and infrapatellar fat pad (Hoffa’s fat pad)—of patients following knee joint replacement. The study also aimed to assess the influence of selected biological and environmental factors on P concentration in studied parts of the knee joint. Phosphorus concentration was determined using inductively coupled plasma-atomic emission spectrometry (ICP-AES). Statistically significant differences in P concentration were found between different elements of the knee joint. The highest P concentration was measured in the spongy bone (72,746.68 mg kg−1 dw) and the lowest in the Hoffa’s fat pad (1203.19 mg kg−1 dw). P levels were unaffected by gender, age, BMI, place of residence, smoking, or alcohol consumption. Data on P concentration in the osteoarticular elements of the knee may be useful in the interpretation and evaluation of biochemical, morphological, and mechanical changes occurring in the body.

Metaphyseal Region

Osteochondroma usually arises from the metaphyseal region of growing bones. The occurrence of extraskeletal osteochondroma is rare with very few case reports. Para-articular osteochondroma is a type of extraskeletal osteochondroma. It frequently occurs around the knee, usually at infrapatellar Hoffa’s fat pad. It is usually intracapsular but extrasynovial and arises from the capsule and connective tissues due to osteocartilaginous metaplasia. We present a case of 19-years male with anterior knee pain for 3 years, swelling, and deformity of the knee with flexion limitation for one year. Radiography revealed ovoid, corticated lesion free from adjoining bones. Mass interpreted as benign, so planned for excision. Well circumscribed nodule excised from the medial parapatellar approach. Histology revealed cartilaginous tissues surrounded by fibrous tissues with scattered enchondral ossification.Postoperatively and subsequent follow-up resulted in pain-free joint, complete recovery of range of motion with no clinicoradiological evidence of recurrence.

Vulva tumors are generally a rare disease encountered in gynecological clinical practice, especially at a young age. Vulvar tumors, more common in the labia major and rarely in the labia minor, clitoris, vestibulum, and posterior comicura. The most common vulvar benign tumors are fibroma, papilloma, lipoma, angioma, and others. A 39-year-old woman, at RSCM Urogynecology Jakarta clinic with chief complain mass or swelling in right labia minor. Size of mass increases in period of one year. Mass began to grow at 8 months of pregnancy. By 2014, patients have same mass in the right and left labia minor, and tumor excision has been performed. Conclusions of the specimens sent for pathological assessment are fibroepithelial papillomas. Gynecological and palpation examinations show 2 solid papilloma masses, in right labia minor, 8x4x2 cm and 3x2x2cm, painless, and firmly defined. In mons pubis area, skin looks coarse, thickened, hyperkeratotic. Speculum examination showed no abnormality. Patient diagnosed as a recurrent minor armored labia tumor. On December 5, 2017 an excision and reconstruction operation was conducted. Obtained pathological exam on December 20, 2017 with results stromal fibroepithelial polyps. Among all tumors in the vulva, tumors in labia minor appear less frequently. Biopsy should be performed for histologic examination to exclude malignant allegations. Furthermore, because of the location and size of the tumor, it can cause severe interference symptoms in the patient and therefore early diagnosis and treatment is essential.

Fibromyxoma represents a rare benign neoplasm that mostly affects the posterior region of the mandible. Here, we report the case of a 46-year-old male with a swelling of the right maxilla. After proper diagnosis, he was treated with enucleation and curettage of the tumor. The defect was filled with a pedicled buccal fat pad flap. The mesenchymal origin from the dental follicle of the fibromyxoma is the most plausible explanation. Radiological examination with MRI, CT, and conventional radiography contributes to the differential diagnosis from other benign tumors, such as the ameloblastoma. Its management is surgical and comprises enucleation and curettage or en bloc resection. Patients must be monitored for at least two years postoperatively in order to diagnose possible recurrence. According to the literature, the maxilla is a rare location of a fibromyxoma and, to our knowledge, our case is the 30th presented case of a fibromyxoma of the maxilla.

Background : It remains unclear whether infrapatellar fat pad (IPFP) excision leads to patella tendon shortening. Shortening of the tendon alters the biomechanics of the knee and can be problematic however current literature is divided regarding the effect of IPFP resect ion on patella length and functional outcomes following total knee replacement. Methods : Our aim was to identify any functional and radiographic differences incurred with IPFP resection. We conducted a retrospective study comparing resection and preservation of the infrapatellar fat pad between 2007 - 2009 using the Stryker Triathlon or Duracon implants between two independent consultant surgeons. 168 consecutive patients were recruited. Baseline demographics were similar between resection and preservation groups with a mean age of 68.5 (70 vs 67, p=0.17), BMI 31.71 (31.02 vs 32.4, p=0.84) and pa tella resurfacing 23.5 (24 vs 23, p=0.29). Results : Comparisons between the resection and preservation groups for the Insall - Salvati, Modified Insall - Salvati, Caton - deschamps and Blackburne - peel ratios preoperatively, at one year and five years postoperat ively did not demonstrate any statistically significant differences. Knee society scores (KSS) preoperatively (45.36 vs 40.5, p=0.31) and at five years postoperatively (90.49 vs 85.31, p=0.2) were not statistically different. Similarly anterior knee pain s cores (AKPS) demonstrated no statistical significance between groups preoperatively (50.6 vs 42.8, p=0.3) and at five years post operatively (69.4 vs 62.0, p=0.88). Conclusion : There is no statistical difference in radiological measures or functional score s (AKPS &KSS) at one or five years post - operatively between resection or preservation of the infrapatellar fat pad following total knee arthroplasty for primary osteoarthritis.

Hepatic Hemangiomas (HH) are benign tumors of the liver consisting of a blood-filled cavity supplied by the hepatic artery. Most of the HH are asymptomatic and are discovered incidentally during radiological imaging of various unrelated pathology. Typical capillary hemangiomas range from a few millimeters to three centimeters and are unlikely to generate any future symptomatology. However, giant liver hemangiomas (more than 10 cm) are a very rare entity and might become symptomatic, hence requiring prompt intervention. We are reporting this case to make the readers aware of the pitfalls and radiological uncertainties while interpreting vascular lesions of the liver. We reported a case of a 21-year-old female with complaint of awareness of a mass over the right upper abdomen since a period of one year which has been gradually increasing in size. On pre-operative Contrast-Enhanced Computed Tomography, features suggestive of Fibrolamellar variant of Hepatocellular Carcinoma was found which was substantiated by biochemical investigations. However, post-operative histopathological examination revealed a capillary hemangioma.

We report two cases of a giant extrasynovial osteochondroma of the knee located in the infrapatellar fat pad region, in two females who were 58 and 71 years old respectively. Both patients had noticed the mass many years before our first clinical observation. In both patients, at physical examination a solid, firm and hard mass was palpable in the anterior part of the knee in Hoffa’s fat pad region, and the range of motion of the knee was severely restricted and painful. CT scan examination with 3D-reconstruction showed two large, calcified neoformations behind the patellar tendon, between the apex of the patella and the proximal third of the tibia. In both cases, the mass was completely resected surgically through an anterior longitudinal approach. At histological examination, the excised masses consisted of an outer layer of hyaline cartilage without significant chondrocyte atypia and an inner region of bone trabeculae formed by endochondral ossification. At follow-up, 8 and 4 years after the operation, both patients were pain-free, with complete recovery of the range of motion of the knee and without any clinical or radiographic evidence of recurrence. The authors believe that intra-articular extrasynovial osteochondroma of the knee is a primary metaplasia of Hoffa’s fat pad. Usually, the tumor develops slowly and asymptomatically over many years. The treatment of choice is a marginal resection of the mass, although a biopsy should be considered in some cases. Recurrences are extremely rare.

Abstract Background Hoffa’s fat pad is a structure located within the fibrous joint capsule of the knee joint, but outside the synovial cavity. It plays an important biomechanical and metabolic role in knee joint, reducing the impact of forces generated by loading and producing cytokines. Changes in its size can induce modifications in the knee homeostasis. However, a great variability exists regarding its measurements. This work aims to evaluate the reliability of a measurement method of Hoffa’s fat pad dimensions through MRI. Methods 3T sagittal IW 2D TSE fat-suppressed MRI sequences, taken from the OAI (Osteoarthritis initiative) database, of 191 male and female patients, aged between 40 and 80 years, were analysed; a manual measurement of the thickness of Hoffa’s fat pad of each subject was then performed by two different readers. The interobserver reliability and intraobserver reliability of the measurements were described by coefficient of variation (CV), Pearson correlation and Bland–Altman plots. Results All statistical analyses have shown that not significant intra- or interobservers differences were evident (intraobserver CV % for the first observer was 2.17% for the right knee and 2.24% for the left knee, while for the second observer 2.31% for the right knee and 2.24% for the left knee; linear correlation was for the first observer r = 0.96 for the right knee and r = 0.96 for the left knee, while for the second observer r = 0.97 for the right knee and r = 0.96 for the left knee; in addition, the interobserver CV % was 1.25% for the right knee and 1.21% for the left knee and a high interobserver linear correlation was found: r = 0.97 for the right knee and r = 0.96 for the left knee). All results suggest that this manual measurement method of Hoffa’s fat pad thickness can be performed with satisfactory intra- and interobserver reliability. Conclusions Hoffa’s fat pad thickness can be measured, using sagittal MRI images, with this manual method that represents, for his high reliability, an effective means for the study of this anatomical structure.
