The tumor had begun as a small nodule approximately 5 years before, and had grown slowly with time. A small, superficial ulcer had appeared on the lesion approximately 6 months previously, and slight bleeding had occasionally occurred. The patient had no pain and no other complaint except bleeding. Dermatologic examination revealed a violaceous, ulcerated, and bleeding tumoral lesion below the mid-portion of the right costochondral line (Fig. 1). The tumor was a non-tender, hemispheric mass, approximately 3-4 cm in size, adherent to the epidermis, but movable on the underlying tissue. An incisional biopsy was performed with diagnoses of dermatofibrosarcoma protuberans and desmoid tumor. Histopathologic examination revealed prominent blood-filled vascular spaces (Fig. 2) and clearly delimited cords, showing two types of cell (Fig. 3). The vascular spaces contained a periodic acid-Schiff (PAS)-positive, granular, eosinophilic material. There was no malignant transformation. The lesion was totally excised and primarily sutured.eninfo:eu-repo/semantics/closedAccess[No Keywords]Article373221223955611410.1046/j.1365-4362.1998.00461.x2-s2.0-0031935066Q2WOS:000072921900015Q3
