ABSTRACT
BACKGROUND:
Histiocytoma or dermatofibroma (DF) is a common benign skin tumour with several clinical and histopathological variants. Sebaceous induction overlying a dermatofibroma is rare and infrequently reported. Using a detailed clinical case, herein the semiological and dermoscopic features of this lesion are described and illustrated, and the differential diagnoses presented. PATIENTS ANDMETHODS:
A 52-year-old man consulted for a physical examination, which revealed a firm papular lesion of the upper middle back. The upper part of the nodule was covered by a slightly hyperpigmented surface, with numerous small whitish lobules. Microscopic examination revealed a dermatofibroma with sebaceous induction.DISCUSSION:
Sebaceous induction overlying a dermatofibroma is not frequent, and it occurs in most cases on or near the shoulder. The typical dermoscopic pattern involves many whitish globules or clumps grouped into clusters. The aetiology is unknown but could stem from a conducive microenvironment in shoulder skin, associated with growth factors secreted by the DF.Palavras-chave
