Primary malignant melanoma of vagina is a rare disease with a predilection for local recurrence, distant metastasis and short survival time. Due to the low incidence and lack of reporting in the literature, treatment choices still remain controversial. We describe 2 cases of vaginal malignant melanoma. A 42 yr old female presented with complaints of post coital and per vaginal bleed of 1 month duration. Examination findings shows growth 6 cm x 6 cm on anterior vaginal wall, another 3 x 3 cm lesion on right lateral vagianl wall. Vaginal biopsy showed malignant melanoma, S-100 and HMB-45 positive while negative for CK and LCA. MRI Whole abdomen showed altered lesion [3.8 cm (AP), 6.0 cm (TR) and 4.9 cm (CC)] in upper 2/3rd of vagina extending into vaginal fornices and abutting right lower cervix superiorly, right paravaginal extension and mesorectal fascia. No significant enlarged lymph nodes were seen. In view of localised disease she underwent Type III Radical hysterectomy with bilateral salpingo-ophorectomy with bilateral pelvic lymphnode dissection with total vaginectomy. Histopathology s/o 2 tumour nodules, one located in the anterior vaginal cuff measuring – 5 x 5 x 3.2 cm, another located in right lateral vaginal cuff measuring 2.5 x 3 x 1.5 cm, malignant melanoma with involvement of the cervix with full thickness stromal invasion (2.8/2.8 cm,) invading perivaginal soft tissue, distance of invasive carcinoma from closest stromal margin R). Vaginal Biopsy was suggestive of Malignant Melanoma, expressing S-100, HMB 45 and SDX-10. Metastatic work up was negative. She underwent RH with total vaginectomy with bilateral PLND with RPLND. HPR showed exophytic black growth seen involving all quadrants of vagina, extending upwards into both lips of cervix – 7 x 6 x 2.5 cm, Malignant melanoma, distance of invasive carcinoma from closest margin |
