MALIGNANT NEOPLASM OF THE KIDNEY: AN UNUSUAL CASE IN CHILDHOOD

Intrahepatic cholangiocarcinoma is a relatively uncommon malignant neoplasm. We recently encountered an unusual case of intrahepatic cholangiocarcinoma that histologically resembled a thyroid carcinoma. A thorough review of the English literature revealed only 2 similar cases that have been previously reported. Immunohistochemical studies are imperative to confirm the diagnosis of cholangiocarcinoma and to exclude the possibility of metastatic thyroid carcinoma and other malignancies with thyroid-like features.

Unusual Case Report

CONTEXT: Ewing's sarcoma is a rare neoplasm, which usually arises in long bones of the limbs and in flat bones of the pelvis, with the involvement of head and neck bones being very unusual. CASE REPORT: a case of Ewing's sarcoma occurring in the mandible of a 35-year-old female. Pain and swelling of the tumor were the main complaints. The early hypothesis was an undifferentiated malignant neoplasm, possibly a sarcoma. The CT scan depicted an expansive lesion, encapsulated, with septa and characteristics of soft tissue, involving the left side of the mandible and extending to the surrounding tissues. The patient underwent surgical excision of the lesion, the definitive diagnosis of Ewing's sarcoma was established, and the patient commenced on radiotherapy.

AbstractA pseudotumour represents a lesion that masquerades as a malignant neoplasm. We present an unusual case where the appearance of a tumour was the result of chronic inflammation stimulated by the presence of food matter. This inflammatory reaction resulted in upper airway obstruction associated with a mass lesion and vocal fold palsy.

Multiple Nodules

The occurrence of cutaneous infiltration by malignancies has been accounted to 0.7 %- 9 % of patients suffering with malignant neoplasm and are generally thought to be a late consequence of most neoplasms.And, the prevalence of malignant melanoma as a primary tumor in one published study was 59 out of 381 patients. We herein report an unusual case of a patient who presented with multiple nodules of varying sizes over the body, which later revealed to be malignant melanoma; both on cytopathology and histopathology examination. As this is a rare, unusual condition in our setting, frequent and timely case reporting is to be done that will ensure the better management and outcome of the disease

Work Up

AbstractAn unusual case of post-radiation primary intranodal leiomyosarcoma of the cervical lymph node is presented. The patient was a 32-year-old white man who was treated in 1986 with hemiglossectomy and right neck dissection, followed by radiation therapy, for squamous cell carcinoma of the tongue. Six years later, he presented with an enlarged left cervical lymph node which on biopsy showed a high grade spindle cell malignant neoplasm. Immunohistochemistry and electron microscopic study verified the smooth muscle origin of the tumour.Extensive work-up for a second primary lesion was negative. Primary intranodal leiomyosarcoma is extremely rare. We briefly discuss the histological differential diagnosis of spindle cell lesions of lymph nodes, leiomyosarcoma of the vessel wall and radiation-associated sarcoma.
