AbstractBackground:Myopericytoma is a relatively recently described skin and soft tissue tumour that demonstrates perivascular myoid cell or pericytic differentiation. Whilst the range of anatomical locations has expanded to include visceral locations, head and neck myopericytomas are rarely documented. There have been no previous reports of aural myopericytoma.Case report:This paper reports the clinicopathological features of a biopsy-proven, slow-growing, 20 × 20 mm, polypoid myopericytoma that involved the external auditory canal and tragus in an 18-year-old woman. Excision was curative.Conclusion:Heightened clinicopathological awareness of the expanding anatomical distribution of myopericytoma is critical to its diagnosis when it presents in unusual and novel locations. Myopericytoma should be added to the range of external auditory canal neoplasms, especially those characterised by an admixture of spindle cells and a prominence of blood vessels, including those with a haemangiopericytomatous pattern.

Abstract PurposeTo describe a very rare case of Synovial Sarcoma affecting cervical spine vertebra.SS is a rare malignant and aggressive soft tissue tumour arising from mesenchymal cells. Primary bone origin SS is a much rarer entity that affects more commonly long bones. Ideal therapeutic strategy is yet to be defined due to very small number of cases reported so far.Case reportA 55-year-old male, construction worker, with no other relevant medical history presented with a progressive tetraparesis after recurring several times during a 4-week period to assistant physician and emergency department complaining about bilateral shoulder pain. Image studies revealed an osteolytic lesion centred on C4 vertebra with intracanalar and intraforaminal extension, causing neurologic compression. Patient was submitted to urgent surgical decompression intervention. C3 and C4 corpectomy and excisional biopsy followed by stabilization with C2-C5 arthrodesis.OutcomesNeurological deficits did not improve after surgery. Histopathological and immunohistochemical analysis revealed phenotypical characteristics of a biphasic Synovial Sarcoma. Patient died 4 weeks after surgery due to a respiratory tract infection.DiscussionSS is a malignant rare and aggressive soft tissue tumour that usually affects young adults. Very few cases of primary bone SS affecting the spine are described in literature. Imaging studies may suggest the diagnosis of synovial sarcoma but definitive diagnosis can only be confirmed by histological and immunohistochemical analysis.The rarity of these lesions demands high clinical suspicion for the diagnosis and due to the low number of cases reported ideal therapeutic strategy is yet to be defined.

Spindle cell lipomas (SCL) are slow-growing benign adipocyte tumours that are most commonly seen in (1) the upper back, posterior aspect of the neck, and shoulders . Both genders are affected, but it is more (1) prevalent in males between the ages of 40 and 70 . Spindle cell lipoma is a benign tumour that is frequently confused with (1) liposarcoma. SCLs account for approximately 1.5 percent of all lipomatous tumours reported, making them uncommon . They (2) have a morphology similar to other benign and malignant fatty/spindle cell or myxoid lesions . Microscopically, it is a complex mixture of lipocytes and uniform spindle cells embedded in a mucinous matrix and traversed by (2) a variable number of birefringent collagen bres . Due to the unusual presentation and similar morphology of tumours, early diagnosis is critical; thus, diagnosis is based on clinical examination and conrmed by histopathological ndings. Because SCL has a favourable prognosis, wide local (1) excision is the treatment of choice . This is a case report of a 52-year-old male with a similar presentation in the right upper limb.

Nodular fasciitis is an uncommon, benign, reactive fibroblastic soft tissue tumour. It is infrequently seen in the hand. A case of nodular fasciitis involving the thumb of a 34-year-old male is reviewed, and its clinicopathologic features are presented. Main significance lies in clinical and pathological recognition of the lesion to avoid over-treatment.

Aggressive Angiomyxoma (AA) is a rare variety of soft tissue tumour of pelvis and perineum occurring almost exclusively in adult females. AA is most often found in or in proximity to the lower pelvis, more specifically perineum, vulva, vagina or inguinal regions. Here we report a case of angiomyxoma. She is a 40 years old house wife, presented with a brownish, soft, multilocular, pedunculated nontender solid mass in the left side of the vaginal wall. Though initially it was provisionally diagnosed as a case of cervical polyp, ultimately histopathology proved it to be a case of Aggressive Angiomyxoma.

Microscopic Features

Myofibroblastoma (MFB) is a rare mesenchymal tumor arising in breast's soft tissue with a great variety of microscopic features that can be mistaken with a wide variety of biphasic lesions. The authors report a rare case of myofibroblastoma of the breast arising in a mammary hamartoma (MH), present a review of the clinicopathological features of these lesions, and make some diagnostic considerations. The tumour consisted of a well-circumscribed nodule. MFB component comprised about fifty percent of the lesion and was made up of bipolar spindle cells arranged in fascicular clusters separated by bands of hyalinized collagen. There were fat cells and several residual hamartoma glands intermingled and distorted in MFB area. MFB component was positive for Desmin, CD34, bcl-2, and Calponin. To the best of our knowledge, MFB has not been reported in MH, neither has any of the reports described mammary glands joined within MFB.
