Case Report: We report a case of papilliferous cystadenoma of the scalp in a 22-year-old adult with no previous history of the disease. She had been presenting with a slowly progressing scalp mass for about 10 years. The mass was mildly pruritic and painless, but the patient reported several painful episodes treated with local herbal applications and unspecified antibiotics. On inspection, the lesion was raised, granular, sessile and vegetated, greyish in color, with an irregular surface, nippled and hemispherical in shape. On palpation, the lesion was painless, fleshy and surrounded by crusts that were easily removed by applying a saline-moistened compress. The patient underwent excision with at least 4-mm margins. Pathological examination of the operative specimen revealed a papilliferous syringocystadenoma. There was no tumor recurrence after three years. Conclusion: Papilliferous cystadenoma is a rare benign tumor of the scalp requiring clinical analysis and surgical excision to confirm its histological nature. Post-operative follow-up is necessary due to frequent recurrences.展开更多

Giant cerebriform nevus of the scalp has a major psychosocial impact because of its unsightly appearance with fetid maceration. We report the case of a 35-year-old woman who had a painless, malodorous swelling of the cerebriform scalp measuring 20 × 17 cm in diameter with a wide base of insertion at the occipital level adhering to the deep planes. The excision associated with a skin plasty was carried out. Histology concluded that there was a giant cerebriform naevo-cellular nevus of the scalp.展开更多
