Occult lymph node metastasis from desmoplastic small round cell tumor diagnosed by fine needle aspiration cytology. A case report.

BACKGROUND: Desmoplastic small round cell tumor (DSRCT) is a rare but well-defined neoplasm generally forming in the abdominal or pelvic cavity of young males and has distinct clinical, immunohistochemical and molecular features. Cytologic features of DSRCT have been described on fine needle aspiration of primary tumors. An occult lymph node metastasis of DSRCT diagnosed through the cytologic features, a basic immunocytochemical panel and DNA ploidy evaluation on cytospins obtained by fine needle aspiration is reported. CASE: Aspiration cytology was performed on an inguinal lymph node from a 20-year-old male. A Diff-Quik-stained smear showed mature lymphocytes and groups of undifferentiated, small cells with scanty cytoplasm, dense and coarse chromatin, and small nucleoli. Basic immunocytochemical stains showed negativity for leukocyte-common antigen and neuron-specific enolase and positivity for cytokeratin cocktail (Cam 5.2), vimentin and desmin, the last with characteristic paranuclear dotlike positivity. DNA ploidy evaluation showed an aneuploid histogram with a low 5c exceeding rate. CONCLUSION: Cytologic and immunocytochemical features suggest the diagnosis of DSRCT on fine needle aspiration cytology samples even in cases of a metastatic, unknown primary tumor. Because of the tumor's aggressiveness, a rapid and accurate diagnosis is required.

Malignant melanoma: correlating abdominal and pelvic CT with clinical staging.

Two hundred two patients with malignant melanoma underwent computed tomography (CT) scanning of the abdomen and pelvis. The frequency of metastases in the abdomen and pelvis was correlated with the site, level, and thickness of the primary tumor. The sites of the primary tumors were the trunk (70 patients), the lower extremities (37 patients), the upper extremities (33 patients), the head and neck (29 patients), the eye (nine patients), and the genitourinary tract (six patients). In 18 patients, the primary site could not be identified. In 96 patients, the level and thickness of the primary tumor, based on Clark and Breslow classifications, were correlated with the presence and extent of metastases. CT showed metastases in 122 patients (60%). The head and neck were the most common primary sites associated with metastases (79%), followed by the eye (77%) and genitourinary tract (67%). Thick lesions had the highest frequency of metastases (84%), compared with intermediate (50%) and thin (46%) lesions. Tumors classified as Clark level V had the highest frequency of metastases (87%).
