Extraskeletal myxoid chondrosarcoma (EMC) is a relatively rare but well-defined neoplasm. This report describes two patients, one with EMC of the buttock and one with EMC of the knee. The two cases presented with large lobed masses and long T1 and T2 signaling identified by magnetic resonance imaging (MRI). An enhanced MRI scan demonstrated enhancement of the tumors. The tumors were composed of...

The q13 to q15 region of human chromosome 12 is frequently and consistently rearranged in malignant and benign adipose tissue tumors as well as benign tumors of smooth muscle and salivary glands. A reciprocal translocation, (12;16) (q13;p11), is characteristic of the myxoid subtype of liposarcoma, whereas translocations within 12q13-14 are frequently observed in benign lipomas. We are using pul...

Adrenal cortical tumors with myxoid change are rare tumors. To our knowledge, only 22 cases have been described so far in literature, which include 13 carcinomas and 9 adenomas. A pseudoglandular pattern has been described in 9 of these tumors. We report a case of a myxoid adenoma of the left adrenal gland in a 67-year-old woman, with a focal pseudoglandular pattern involving about 20% of the s...

A case report of myxoid leiomyosarcoma of the uterus in a 54-year-old woman is presented as a rare variant of uterine sarcoma. Only 14 cases have been described in the literature. These tumors have a striking myxoid appearance and exhibit highly malignant behavior despite their low mitotic index. Although it is difficult to establish the nature of the neoplastic cells in the myxoid areas, both ...

Skin tumors occurring on the scleroderma fingers are rarely seen. Swollen fingers are hallmarks of systemic sclerosis, and mucin deposition in the lesional skin is a constant feature in systemic sclerosis. Here we describe a case of cutaneous myxoid cyst on the flexor aspect of the sclerotic fingers in a patient with severe diffuse cutaneous systemic sclerosis. Cutaneous myxoid cyst is a relati...

Endometrial stromal sarcoma (ESS) is the second most common malignant uterine mesenchymal tumor. It affects women primarily in the perimenopausal age group. ESSs are morphologically heterogeneous. The distinction between uterine smooth muscle tumors such as cellular leiomyoma and myxoid leiomyosarcoma and low-grade ESS can be problematic when stromal sarcomas show prominent smooth muscle differ...

Chondromyxoid fibroma (CMF) is one of the rarest benign tumors of cartilaginous origin. It accounts for less than 0.5% of bone tumors and less than two percent of benign bone tumors. It is composed of a mixture of chondroid, myxoid, and fibrous tissues. The diagnosis of CMF depends upon its characteristic histological appearance like a lobular pattern with stellate-shaped cells in a myxoid or c...

Dermatofibrosarcoma protuberans is a locally aggressive skin tumor that affects young and middle-aged adults. A number of histological variants have been described, the myxoid type being one of the least common. Microscopically it is formed of a neoplastic growth that is located in the dermis and hypodermis and has a predominant myxoid component. Peripherally there are infiltrating bundles of s...
