RESUMO
BACKGROUND: Nodular fasciitis is a benign pseudosarcomatous, self-limited, and reactive process. Based on its clinical and histological features - a fast-growing, solitary tumor with high cellularity and mitotic count - nodular fasciitis is considered to be a benign mimic of sarcoma. METHODS: We present four cases of nodular fasciitis and a review of the literature. RESULTS: The cases we present were initially misdiagnosed as sarcoma; two as dermatofibrosarcoma protuberans, one as atypical fibroxanthoma, and one as leiomyosarcoma. CONCLUSION: Awareness of this entity among dermatologists is important as misdiagnosis may lead to unnecessary treatments associated with increased morbidity.

Albino patients are at great risk for developing cutaneous neoplasms, including melanomas. In this paper we describe the dermatoscopic findings of nevi in two patients with oculocutaneous albinism type Ia (OCA-Ia) highlighting that they manifest a vascular pattern similar to that described for amelanotic melanoma. We propose managing these patients with dermoscopy, using the comparative approach, digital follow up (DFU), and reflectance confocal microscopy as a complementary tool for difficult cases.
