Primary melanoma of the ovary in a 25 year old primigravida--a case report

A 25 year old primigravida with edema of the left foot and fetal distress during 36 weeks gestational period underwent an emergency lower segment cesarian section (LSCS). During surgery ascites and a left ovarian tumor with omental seedlings were observed. Cytopathology of the ascitic fluid, histopathology of the ovarian tumor and the omental seedlings showed features of a malignant melanoma, further confirmed at electron microscopy. Considering the age of the patient and the intra-abdominal restriction of metastasis of the neoplasms this tumor appeared to be a primary melanoma of the ovary. This case is reported since there is no reference to a pure melanoma of the ovary occurring in a young primigravida in the literature.
