RESUMEN
Abstract: Dermatofibrosarcoma protuberans is an uncommon neoplasm that is most often seen in young adults. The most common clinical presentation is the protruding form; however, other subtypes are known, such as the atrophic. In 2012 there were only 33 reports of this variant in the literature. Many cases of Dermatofibrosarcoma protuberans in children are only discovered in adulthood because they were not diagnosed early. Due the high morbidity, we raise the need for attention from the dermatologist to recognize uncommon neoplasms in the clinical practice. We report a case of a 15-year-old patient diagnosed with atrophic Dermatofibrosarcoma protuberans on the back.

Abstract: Syringocystadenoma papilliferum and tubular apocrine adenoma are rare benign sweat gland tumors. Syringocystadenoma papilliferum occurs alone or in association with other tumors. Although it is rare, the association of tubular apocrine adenoma with syringocystadenoma papilliferum developing in a sebaceous nevus on the scalp is well documented. However, the co-existence of these two tumors without the background of a sebaceous nevus has not been frequently reported. Syringocystadenoma papilliferum and tubular apocrine adenoma may have a histopathological overlap, but a few cases of a syringocystadenoma papilliferum combined with a tubular apocrine adenoma have been reported. Herein we describe an unusual case of syringocystadenoma papilliferum co-existing with a tubular apocrine adenoma located on the back of a 14-year-old patient in the absence of a pre-existing sebaceous nevus.
