Choriocarcinoma is a rare neoplasm and a malignant form of gestational trophoblastic disease. Invasive mole may perforate uterus through the myometrium resulting in uterine perforation and intraperitoneal bleeding. But uterine perforation due to choriocarcinoma is rare. We present a case of a young woman who presented 1 year after uterine evacuation of a molar pregnancy with invasive choriocarcinoma complicated by a uterine rupture and haemoperitoneum.
Gestational choriocarcinoma is a rare neoplasm of pregnancy that is often undiagnosed until the advanced stage manifests with metastatic complications. Herein, we present a case of a 22-year-old young woman with metastatic gestational choriocarcinoma with unidentified primary origin, who presented with haemoptysis as a chief problem in her third trimester. The case emphasises on the rarity of this neoplasm in a viable pregnancy. Prompt diagnosis and treatment is the key for good maternal and fetal prognosis.
Abstract
This article provides an overview of the pathology of alveolar soft part sarcoma, focused on its morphology, special stains useful in diagnosis, and the clinical and radiographic features of the disease. Alveolar soft part sarcoma is a rare neoplasm of unknown histogenesis with poor prognosis. Although there are several immunohistochemical stains available to help reach the diagnosis, the morphology of the tumor should be considered the main diagnostic feature. The periodic acid–Schiff stain is the best single stain that supports the diagnosis.
Primary malignant melanoma of the oral cavity is a rare neoplasm. The tumors tend to metastasize or locally invade tissue more readily than other malignant tumors in the oral region. The survival of patients with mucosal melanomas is less than for those with cutaneous melanomas. Tumor size and metastases are related to the prognosis of the disease. Early detection, therefore, is important.
We report the case of a glomus tumor originating in the left main bronchus diagnosed in a 79 year old Caucasian man. A glomus tumor is an extremely rare neoplasm in the bronchi with nonspecific clinical features. Bronchoscopy allows the diagnosis through biopsy and subsequent histopathological examination of the tissue and in selected cases may represent a valid alternative to surgery permitting a radical tumor excision.
