HighlightsCarotid body tumors are rare neuroendocrine neoplasms derived from neural crest cells.MRI imaging is considered to be the gold standard criterion for carotid body tumors diagnosis.Surgical resection of carotid body tumors represents a special challenge to the surgeon.

Highlights Schwannomas are neural crest tumors. Incidence extremely rare in the retroperitoneum. Inmunochemistry is needed for final diagnosis.

Dermatofibrosarcoma protuberans (DFSP) is a malignant skin neoplasm of slow growth characteristics. A case of inguinal DFSP is presented in order to review clinical diagnosis challenges, histological variants, malignancy behaviour and therapeutic modalities. Although rare in frequency of presentation, its high recurrence rate and metastatic potential make it an important tumor for the general surgeon to keep in mind.
