Introduction: Pilomatrixoma is a relatively rare, benign tumor arising from the hair root matrix. It is found frequently on the head and neck, with most involving the eyebrow in the periocular region. In contrast, eyelid pilomatrixoma is less common, and often clinically misdiagnosed. Here, we present clinical and histological data from 19 pilomatrixomas arising in the eyelid. Methods: The study represents a retrospective study of eyelid pilomatrixoma diagnosed at our institution since 1981. All slides were reviewed, and demographic as well as clinical data obtained. Results: Patient ages ranged from 2 to 63 years (mean 24 years), including 12 (63%) females and 7(37%) males. Eight (42%) and 4 (21%) cases arose in the first and second decades of life, respectively. Upper eyelid involvement was found in 14 (74 %) of cases. Microscopically, the tumors were characterize by basaloid and shadow cells accompanied by calcification and foreign body giant cells. Conclusions: Eyelid pilomatrixoma is rarely suspected clinically, and can be mistaken for cyst, chalazion, sebaceous carcinoma and other tumors. Physicians should consider the possibility of pilomatrixoma in the eyelid area, especially in children or young female patients. Complete excision is curative, and diagnosis can generally be established by histopathological examination.

A six year old crossbred male dog presented with non-pigmented, pale pink, unhaired, ulcerative tumor of the medial canthus and upper eyelid region. As treatment, surgery was proposed. During the surgery complete excision of the tumor was performed. The extent of skin loss, especially in the upper eyelid required plastic reconstruction by pedicle flap transposition. The soft skin of the cheek was chosen as a graft donor site. The postoperative period proceeded without any complications and ended with successful engraftment. The soft cheek skin did not impede movement of the upper eyelid. Histopathological examination indicated histiocytoma and tumor-free excisional margins were confirmed. There has been no recurrence during the subsequent 12 month period.

AbstractPhaeohyphomycosis is a collective term used for fungal infections caused by moulds and yeasts that have brown pigmented cell walls due to the presence of melanin. These are also known as dematiaceous fungi. We report this patient who presented with headache, right hemiparesis, slurred speech, and altered sensorium. Patient was a known case of rheumatic valvular heart disease (RVHD) and had undergone balloon valvotomy for mitral stenosis 1 year back. Radiological features were suggestive of high grade glioma. Left fronto-parietal decompressive craniectomy with complete excision of mass lesion was performed. Histopathological examination of the surgical specimen revealed multiple granulomas with giant cells. These giant cells contained branched septate pigmented fungal hyphae in their cytoplasm. After the histopathology report, patient was started on intravenous amphotericin and was discharged on oral itraconazole 200 mg twice daily. Unfortunately, the patient was non-compliant and stopped taking oral itraconazole after 1 month. He landed up in fulminant fungal meningo-encephalitis and died 10 weeks after the initial diagnosis. We report a rare case of cerebral phaeohyphomycosis in a patient of RVHD which, to our knowledge, is nowhere mentioned in the literature.

Rare Benign Tumor

Peripheral odontogenic fibroma (POdF) is a rare benign odontogenic tumor of ectomesenchymal origin which is composed of fibrous connective tissue containing islands, strands or cords of odontogenic epithelium. The lesion is more common among females, commonly seen between the second to fourth decades of life, mostly affecting the anterior region of mandible. Clinically, it may present similar characteristics with other more common gingival lesions such as pyogenic granuloma, peripheral ossifying fibroma and peripheral giant cell granuloma. So, histopathological examination is required for accurate diagnosis. We present here three rare clinical cases of peripheral odontogenic fibroma and their management by complete excision of the lesion with good postoperative outcomes.

Intestinal tuberculosis (TB) most commonly affects ileo-caecal region. Isolated gastric and duodenal involvement without pulmonary infection is rare. The presentation of these patients varies. Patients may present with haematemesis, non-healing chronic ulcer, mimicking malignancy, gastric perforation and gastric outlet obstruction. High degree of suspicion is needed for early diagnosis of gastro-duodenal TB. A young female patient who was being treated as a case of nonhealing chronic ulcer was referred for treatment. Histopathological examination of endoscopic biopsy specimen of the patient showed presence of granulomas composed of epitheloid cells and Langhan’s giant cells with caseation with no evidence of tuberculosis at pulmonary or other body sites. After anti-tubercular chemotherapy there was resolution of symptoms and healing of ulcers. This case of isolated gastro-duodenal TB is reported for its rarity. J Enam Med Col 2019; 9(3): 189-192

Eurasian otters Lutra lutra are listed as Near Threatened on the IUCN Red List and are imperiled by habitat loss, water pollution, and poaching. Harassment and attacks by stray animals are also recognized threats to the health of wild Eurasian otters. Pulmonary hair embolism is a possible complication in animals with deep traumatic injury, but to date no cases have been reported in wildlife. A free-ranging, adult male Eurasian otter was rescued due to severe emaciation and multiple bite wounds. The otter died 3 d after rescue and was necropsied. Grossly, a 1.5 × 1.5 × 1.5 cm firm nodule was observed in the left cranial lung lobe. Histologically, a fragment of hair shaft surrounded by multinucleated foreign body giant cells was observed in a medium-sized vein, and extensive eosinophilic infiltration was noted in the adjacent vascular wall and lung parenchyma. Based on the gross and histological findings, the pulmonary lesion was consistent with eosinophilic pneumonia and vasculitis induced by hair embolism. The presence of well-formed multinucleated foreign body giant cells and eosinophils may imply a late stage of foreign body reaction, and thus the presumptive source of hair embolism is an animal bite. This is the first report of pulmonary hair embolism associated with animal bite in a rescued free-ranging Eurasian otter.

Chitosan Powder

Background Sternotomy is a standard approach performed in almost every surgical procedure on the heart and mediastinum. Effective hemostasis of the sternum is required to keep the operative field dry, avoid excessive blood transfusions during surgery, and prevent reoperation due to massive postoperative bleeding, which can further increase morbidity and mortality in patients. Bone wax is a mechanical hemostat commonly used after sternotomy and has been known to affect bone healing, trigger chronic inflammatory reactions, and increase the rate of infection. The application of chitosan, which has intrinsic hemostat ability, as hemostatic material is believed to improve bone healing following sternotomy. This study aimed to compare the effectiveness of bone wax and chitosan on bone healing after sternotomy. Methods Median sternotomies were performed on 2 groups of New Zealand White rabbits. Each group of 16 animals received either bone wax or chitosan powder as hemostatic material. The degree of bone healing, the number of foreign-body giant cells, and the number of osteoblasts were evaluated after 6 weeks. Results Radiographs showed that significantly more animals in the chitosan group had total sternal healing ( p = 0.033). Histopathology revealed that the number of foreign-body giant cells was significantly less ( p = 0.036) and the number of osteoblasts was significantly greater ( p < 0.0001) in the group of animals that received chitosan. Conclusion The use of chitosan as hemostatic material can promote better bone healing compared to bone wax.

Clinical Differential Diagnosis

Tuberculosis of the oral cavity which is an uncommon occurrence can be primary or secondary. In the absence of active pulmonary tuberculosis, isolated tonsillar tuberculosis is rare. Herein, we report two cases of bilateral tonsillar tuberculosis who presented as recurrent sore throat for which tonsillectomy was done. No active primary pulmonary lesion was found in these cases. Histopathological examination revealed caseating epithelioid granulomas with Langhans giant cells. Ziehl Neelson stain for acid fast bacilli was positive in one case. Tonsillar tuberculosis, though a rare entity, should be considered in the clinical differential diagnosis of tonsillar lesions. Histopathological examination with Ziehl Neelson stain should be performed for definite diagnosis.

Abstract: Diagnosis of sporotrichosis associated with lymphocutaneous nodules was made based on the histopathological examination of skin lesions and the cytology of fine needle aspiration biopsy (FNAB). A case of sporotrichosis in a 63-year-old man was reported with papules and nodules spread along the back of the left hand, forearm, and arm. The histopatho-logical examination showed infiltration of PMNs, granulomas, and giant cells in the dermis and epidermis, along with hyperplasia and microabscesses. Sporothrix schenckii was not found in the skin lesion tissues. However, in the FNAB cytology examination of lymphocutaneus nodules we found spores of Sporothrix schenckii in the cytoplasma of histiocytes besides granuloma and infiltration of PMNs. Key words: sporothrix schenckii, histopathology, FNAB cytology.  Abstrak: Diagnosis sporotrikosis kulit dengan nodul limfokutan ditegakkan melalui pemerik-saan histopatologi pada lesi kulit dan sitologi biopsi aspirasi jarum halus pada nodul limfo-kutan. Kami melaporkan kasus sporotrikosis pada laki-laki berusia 63 tahun dengan papul-papul dan nodul-nodul eritematosa pada dorsum manus, antebrakium, dan brakium sinistra. Pemeriksaan histopatologi jaringan biopsi dari lesi kulit menunjukkan reaksi radang, gambaran granuloma, dan sel datia dalam dermis dan epidermis, dengan mikroabses disertai hiperplasia. Tidak ditemukan jamur Sporothrix schenckii dalam potongan jaringan histopatologi. Hasil pemeriksaan sitologi biopsi aspirasi jarum halus pada nodul limfokutan memperlihatkan adanya spora-spora jamur Sporothrix schenckii dalam sitoplasma sel-sel histiosit disamping  terdapatnya bentuk granuloma dalam infiltrat radang. Kata kunci: sporothrix schenckii, histopatologi, sitologi biopsi aspirasi jarum halus.

A 59-year-old female living in Rayong Province, eastern Thailand, presented with painless, right upper eyelid nodule for 3 months. Upon removal of the eyelid mass, a well-circumscribed, firm globular mass with diameter about 1 cm was found. Histopathological examination revealed an immature female dirofilarial worm reminiscent of Dirofilaria repens, characterized by prominent sharp longitudinal ridges at external surface of the cuticle. Analysis of the mitochondrial 12S rRNA sequence showed that the worm belongs to Candidatus Dirofilaria hongkongensis. It is likely that some infections previously reported as D. repens based on histological examination may have actually been due to Candidatus D. hongkongensis.
