Abstract
BACKGROUND:
Ulceration and osteoclast-like giant cells are two pathological features uncommonly seen in dermatofibromas. To our knowledge, the presence of these features has not been previously described within the same lesion.
METHODS:
We report the clinical, histopathological and immunohistochemical findings of a 38-year-old man with an ulcerated dermatofibroma (DF) on the sole containing OLGC.
COMMENTS:
DF, or cutaneous fibrous histiocytoma, is a frequent dermatological lesion with many clinicopathological variants. Therefore, a correct diagnosis is not always straightforward, especially when two rare features co-exist in the same lesion. Differential diagnosis was performed with cutaneous and even non-cutaneous lesions. An explanation for the clinicopathological findings is also described.
