  • Title: Fine-needle aspiration cytology of desmoplastic malignant melanoma metastatic to the parotid gland: case report and review of the literature.
    Author: Chhieng DC, Cangiarella JF, Waisman J, Cohen JM.

    Abstract:
    We report a case of desmoplastic malignant melanoma metastatic to the parotid gland initially evaluated by fine-needle aspiration. The cytologic findings consisted of scattered spindle cells in a background of heterogeneous lymphoid cells. The spindle cells were scant and displayed mild cytologic atypia. In addition, rare stromal fragments were also present. Cytoplasmic pigment and intranuclear cytoplasmic inclusions were not seen. The initial impression was that of a reactive lymph node with fibrosis. In retrospect, rare spindle cells displayed moderate atypia. In addition, the stromal fragments were cellular and contained spindle cells with mild atypia. These cytologic findings along with a known history of malignant melanoma should provide clues to the correct diagnosis of desmoplastic malignant melanoma. Diagn. Cytopathol. 2000;22:97-100.
