Clear cell hydroadenocarcinoma is a very rare sweat gland tumor. It has an aggressive course and high recurrence rate. Wide excision the first option in treatment of this tumor with rate metastasis. Subsequent radiotherapy chemotherapy are still controversial. In case, we presented patient who was operated on lipoma-like appearance scalp. The pathology result hidradenocarcinoma. We emphasized t...

We report what may be the first case of lipoma of the corpus callosum associated with a distal anterior cerebral artery saccular aneurysm. The pathogenetic correlation between the callosal lipoma and the distal anterior cerebral artery saccular aneurysm is discussed.

Lipomas are usually encapsulated benign tumors with slow growth (that begins in adipocytes. They occur mostly in adults, regardless of race or sex, with a slight female predominance in some studies. Lipoma is called giant lipoma when the resection specimen is greater than five centimeters. Cervical-dorsal cord lipoma are rare. We report the case of a 40-year old patient, presenting with cervica...

BACKGROUND AND PURPOSE Pericallosal lipomas are rare tumors. Few reports have included their imaging characteristics. Furthermore, little is known about their evolutive course. Our purpose was to describe the imaging features of seven cases of pericallosal lipoma diagnosed in utero and followed up after birth. METHODS We reviewed seven cases of pericallosal lipoma diagnosed by obstetric sonog...

BACKGROUND Well-differentiated liposarcoma (WDL)/atypical lipomatous tumor (ALT) is considered a low-grade malignancy that rarely metastasizes but should be carefully followed because recurrence or dedifferentiation may occur. It is recognized that WDL and ALT are essentially synonymous, describing lesions that are identical both morphologically and karyotypically, and that site-specific variat...

INTRODUCTION Intraosseous lipoma is a rare benign bone disease. Long and cancellous bones are the most locationsthat can be affected. Almost all lesions were discovered incidentally on imaging modalities that were done during an unrelated investigation. As it is rare, it may be mistaken for nonossifying fibroma, aneurismal bone cyst, simple bone cyst, bone infarct or chondroid tumors. Recently ...

BACKGROUND Lipomas are benign neoplasms arising from adipose tissue. Oral lipomas have been reported in the buccal mucosa, tongue, floor of the mouth and lips; however, the case of a lipoma occurring as an antecedent lesion to recurrent sialadenitis is hitherto unreported in the English literature. CASE PRESENTATION We report the case of an intraoral lipoma occurring with signs and symptoms o...

Squamous cell carcinomas (SCC) with an infiltrative invasion pattern carry a higher risk of treatment failure. Such infiltrative invasion may be mediated by a mesenchymal-like subpopulation of malignant cells that we have previously shown to arise from epithelial-mesenchymal transition (EMT) and resist epidermal growth factor receptor (EGFR) targeting. Here, we show that SCCs with infiltrative,...

The case of a 2-year-old boy with a right middle ear lipoma and a concomitant chondroma of the left external auditory canal is presented. The patient’s preoperative diagnosis was cholesteatomas of the right middle ear and left external ear canal. A right-sided epitympanotomy was performed. A lump of fatty tissue in the right anterior middle ear cleft that obstructed the Eustachian tube orifice ...

A 49 years old male patient who suffered from deterioration of posterior neck pain, left hand numbness, left lower limb pain and gait disturbance for 3 years visited our outpatient department. He had been diagnosed as non-dysraphic cervical intradural lipoma and operated in August 1990. On the radiologic images, we found the regrowth of non-dysraphic cervical intradural lipoma from C2 to C7 lev...
