[Follicular basaloid hamartoma localized in the sacral region with papular plaque-type]. / Hamartome basaloide folliculaire localisé en plaque papuleuse de la région sacrée.

INTRODUCTION: Basaloid follicular hamartoma is a benign tumor with superficial dermal proliferation of thin basaloid cords in a fibrous stroma. CASE REPORT: A congenital case with sacral plaque-like papules is described. DISCUSSION: Three different forms have been reported: a solitary form (usually an alopecic scalp plaque), a generalized acquired form associated with myasthenia, and a linear form. Histological diagnosis may be difficult and require clinico-pathological evaluation.

[Melanotic schwannoma. A case with review of the literature]. / Le schwannome mélanotique. Une observation avec revue de la littérature.

The authors report a case of melanotic schwannoma in a 46-year-old man after 2 years of bilateral sciatica. Surgical removal was incomplete, because of the posterior site of the tumor. The patient was alive and well, 2 years after surgical removal, with some surgical sequelae. The authors stress the diagnostic difficulties of this melanotic and review the previously reported cases in a comparative study.
