ABSTRACT
@#Mucoepidermoid Carcinoma (MEC) is an epithelial malignant tumor that was first described as a salivary gland malignancy. Though common in salivary gland, it is extremely rare in the vulva with only 2 cases reported in the English language literature and none yet in the Philippines. Due to its low incidence, prognosis and definitive management is still unclear. This is a case of a 68-year-old woman with a history of vulvar pruritus and vulvar mass at the left labia majora. Punch biopsy and review of slides revealed Invasive Squamous Cell Carcinoma, Non-Keratinizing type. She underwent Radical Vulvectomy and Bilateral Lymph Groin Dissection; Wide Excision of Perineal Area; Protective Transverse Loop Colostomy; Gracilis Myocutaneous Flap with Identification of Right and Left Median Circumflex Artery with a final histopathology report of Primary Cutaneous MEC of the vulva with lymph node metastasis.

Mucoepidermoid carcinoma is a rare disease that usually occurs in the salivary gland. In extremely rare cases, it can originate from the skin. These cases are more aggressive than the usual mucoepidermoid carcinoma, so they have high mortality and high recurrence rates. Herein we report a case of primary cutaneous mucoepidermoid carcinoma on the cheek. A 34-year-old man had a 1.0x1.0 cm sized cystic lesion. This lesion displayed central erosion and oily discharge. He had been operated on 4 times at a private hospital, but the lesion had recurred. Histopathologically, there were many tumor islands that consisted of mucoid cells, epidermoid cells, intermediate cells and clear cells. The tumor islets showed mild positivity for Alcian blue (pH 2.5), PAS, and d-PAS stain. There was no parotid tumor on the neck-CT scan, nor on positron emission tomography. We therefore diagnosed this cheek lesion as primary cutaneous mucoepidermoid carcinoma, and it was removed completely.
