Primary ovarian leiomyosarcoma in a postmenopausal woman diagnosed using immunohistochemistry / Philippine Journal of Obstetrics and Gynecology

@#Primary ovarian leiomyosarcoma is a very rare tumor which is most commonly seen in postmenopausal women. Primary ovarian leiomyosarcoma has a very poor prognosis, with less than 20% of patients being alive at 5 years. The case is a 51‑year‑old female who presented with a lower abdominal mass secondary to an ovarian new growth. An exploratory laparotomy, peritoneal fluid cytology, unilateral salpingo‑oophorectomy with malignant frozen section of affected ovary, which revealed malignant tumor, proceeded with surgical staging total abdominal hysterectomy contralateral salpingo‑oophorectomy, then proceeded to complete surgical staging with infracolic omentectomy, Jackson‑Pratt drain insertion was performed. Microscopic and immunohistochemical findings established the diagnosis of primary ovarian leiomyosarcoma. Surgery is the cornerstone of treatment, while the role of chemotherapy and radiotherapy is still not clear because substantial data are lacking. The prognosis of primary pure ovarian leiomyosarcomas is extremely poor and there is no established treatment modality for this rare type of tumor.

A case report on primary Cutaneous Mucoepidermoid Carcinoma of the vulva and its clinico-pathologic identity / Philippine Journal of Obstetrics and Gynecology

@#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.
