Malignant melanoma and granulomatosis.
Sarcoidosis or granulomatous reactions have rarely been reported in association with malignant melanoma (MM). We describe seven patients who presented with both granulomatous disease and MM, and discuss the physiopathological and prognostic significance of this association. In three patients, the granulomatosis was diagnosed as true sarcoidosis and in one patient, as tumour-associated granuloma. In three cases, designated here as atypical tumour-associated granulomatoses, the presence of clear-cut pulmonary granulomatous nodules was typical neither for sarcoidosis nor for tumour-associated granuloma and was highly suggestive of melanoma metastases. Mediastinal lymphadenopathy was present in every patient. In all seven patients, the question of mediastinal or pulmonary involvement or relapse of the MM was raised, but could be confirmed in only one patient. MM can be associated with granulomatous disease. Knowledge of this association has implications in the management of patients with MM.
