Vaginal rhabdomyoma: a case report of an uncommon and misleading neoplasm.

Vaginal rhabdomyoma is an extremely rare tumor which presents as a vaginal polypoid masses. It is essential to differentiate it from benign and malignant mimickers so that appropriate therapy may be provided. The present report describes a vaginal wall nodule of a symptomatic 24-year-old woman. Local excision and subsequent pathological examination were performed. The final diagnosis was vaginal rhabdomyoma. The literature is reviewed and differential diagnosis are discussed.

Neuroglial heterotopia of the scalp.

Heterotopic glial nodules of the scalp are non hereditary congenital malformations composed of mature brain tissue isolated from the cranial cavity. The majority of these lesions are found in the nasal region and occur rarely on the scalp. They are frequently diagnosed in newborn infants. However, they may rarely be found in adults. The pathogenesis of these lesions remains unknown. We describe the case of a temporal scalp nodule in a 50 year-old man. At the time of the excision, the mass was not associated with intracranial connection. Histological examination revealed neural tissue staining with S100-protein and the glial fibrillary acidic protein (GFAP).

Pinkus tumour: an unusual case.

Fibroepithelioma of Pinkus is a rare cutaneous tumour. Its classification is controversial and is considered as a variant of either basal cell carcinoma or trichoblastoma. Its presentation as a multiple tumour is rare. We are reporting such a case occurring in a 55-year-old man presenting with multiple seborrheic keratosis-like lesions corresponding histologically to Pinkus tumours. The clinical diagnosis of Pinkus tumour represents a challenge. Histological examination is extremely useful in aiding in the diagnosis of difficult cases.
