The surgical pathology archives were searched for consecutive cases of uterine atypical leiomyoma from 1992 to 2003. Our study indicates that distinct expression patterns for p16, p53, and Ki-67 exist between leiomyosarcoma and usual LM and CLM (P<0.0001).

Diagnostic clues to Melanoma: 1. spp.) Spitz naevus may pose great diagnostic difficulty due to clinical, dermatoscopic and histologic features resembling melanoma.Though usually seen in children, Spitz naevi may arise in adults. TRAUMATIC NEUROMA: Traumatic neuroma is an exuberant non-neoplastic proliferation of nerve endings in response to trauma or surgery.In a severed or injured nerve, if the proximal and distal stumps are not approximated (or if there is no distal stump), haphazard proliferation of Schwann cells at the proximal stump gives rise to a traumatic neuroma.
