Abstract Diabetic fibrous mastopathy (DFM) is a rare benign fibrotic disease of the breast that develops in patients with longstanding and often uncontrolled diabetes mellitus. Clinically, may present an irregular, firm, palpable mass, which be solitary or multiple, occurring one both breasts. occurs most premenopausal women heterogeneously extremely dense breasts; mammography show focal asymme...

purpose: to report the clinical and histopathological features of recurrent atypical fibrous histiocytoma of the corneo-scleral limbus followed by intra-epithelial squamous neoplasia. case report: a 25-year-old female patient presented with a recurrent vascularized gelatinous mass in the left nasal limbus. the preliminary histopathological diagnosis of the previously excised lesion was an amela...

a 10-year-old boy was referred to us for evaluation of fuo accompanied with bone pain in both calves. three hours after intravenous injection of 13 mci of 99mtc-mdp, whole body scan in multiple spot views was performed. the scan showed symmetrical areas of diffusely increased tracer uptake in multiple long bones. histopathologic evaluation confirmed osteosclrosis and fibrotic changes without an...

Although the histopathologic umbrella-like appearance of the epidermis in actinic keratosis (AK) is well known, its histopathogenesis has remained unknown. The author suggests that the penetration depth of ultraviolet B (UVB) radiation can account for such a histopathologic feature by affecting specific epidermal stem cell pools, as the stem cells in the epidermis and the bulge stem cells and s...

PURPOSE To report a unique case of primary corneal melanoma. METHODS A 59-year-old white woman underwent keratectomy to remove a pigmented rapidly enlarging growth on the corner of her left eye. The specimen was submitted for histopathologic examination. RESULTS Ophthalmic examination disclosed no association with limbal or conjunctival melanocytic abnormalities.

Recanalization of intracranial aneurysms following endovascular coiling remains a frustratingly common occurrence. An understanding of the molecular and histopathologic mechanisms of aneurysm healing following coil embolization is essential to improving aneurysm occlusion rates. Histopathologic studies in coiled human and experimental aneurysms suggest that during the first month postcoiling, t...

BACKGROUND Intracranial tumors with heterogeneous histopathology are a well-described pathologic entity. Pathologically, distinct tumors in direct contact with one another, also known as collision tumors are exceptionally rare, and collision between meningioma subtypes has not been previously described in the literature.
