This article presents a rare case of Merkel cell carcinoma (MCC) of the skin. This tumor is also known as trabecular carcinoma or cutaneous small cell undifferentiated carcinoma (CSCUC). This patient had a palpable non-tender mass in her right upper thigh and a large palpable lymph node in the right inguinal area. Microscopic examination revealed Merkel cell carcinoma (MCC) in the skin of the upper thigh as well as in the inguinal lymph node. Immunoperoxidase stains confirmed the diagnosis. Due to its aggressiveness and very unfavorable prognosis, prompt diagnosis and adequate treatment are essential. Wide local excision with adequate margins followed by radiation therapy is the treatment of choice.
An extremely rare case of pulmonary epitheloid hemangioendothelioma (PEH), previously known as intravascular bronchoalveolar tumor (IVBAT), in a 38-year-old female is presented. This patient had a history of rheumatoid arthritis and bilateral multiple small pulmonary nodules which progressed over the years. The histopathological diagnosis of PEH was confirmed by immunohistochemical stains. Prognosis of this tumor is very unpredictable. There is no effective treatment for pulmonary epitheloid hemangioendothelioma.
This article presents a rare case of well-differentiated papillary villoglandular adenocarcima of the uterine cervix. This patient had vaginal bleeding and her disease was limited to the cervix. Since 1989, a total of 41 cases have been reported in the literature as a distinct entity. In the past, this tumor was included with other varieties of adenocarcinomas of the cervix and not as a separate entity. Due to its excellent prognosis, papillary villoglandular adenocarcinoma of the cervix, may be treated by a procedure less radical than a hysterectomy when the tumor is superficial with no vascular or lymphatic invasion. Recognition of this entity and separation from other varieties of adenocarcinomas of the uterine cervix are warranted.
This article presents a rare case of metastatic glioblastoma multiforme (GM) to the cervical lymph node. In spite of very aggressive tumor behavior, extracranial metastasis from intra-cerebral GM is rare. Only a few cases are reported in the world literature. This infrequent extracranial metastasis may be due to the fact that patients do not live long enough to manifest metastases or result from the fact that brain tissue has some structural differences from other tissues in the body. This tumor can be easily mistaken for other anaplastic tumors like malignant melanoma, malignant lymphoma, or anaplastic carcinoma. Positive glial fibrillary acidic (GFA) protein stain (an immunoperoxidase stain) of this metastatic tumor can eliminate all other time consuming, expensive, and exhausting procedures for the patient.
