Epithelioid sarcoma is a rare but aggressive soft tissue that presents significant diagnostic and management challenge to clinicians. We report 31-year-old female who presented with non-healing ulcer of three years’ duration on her left thumb after burn. Examination revealed an ulcerative tumour invading the bone areas haemorrhage. Microscopic examination showed epithelioid neoplasm central nec...

Kaposi's sarcoma is a neoplasm of multifocal origin apparently derived from fibroblastic and vascular elements and predominantly involving the skin. In 10 to 20% of patients with the neoplasm, associated lesions may occur in the lymph nodes, gastrointestinal tract, liver, lungs, heart, bone, and spleen in order of decreasing frequency. Kaposi's sarcoma in a previously healthy person occurring i...

Kaposi's sarcoma (KS) is a malignant vascular neoplasm that typically appears opportunistically in patients with acquired immunodeficiency syndrome (AIDS); it can also arise organ transplanted subjects and exceptionally carriers of autoimmune diseases, such as Behçet's disease. A 23-year-old man disease who debuts clinically histologically compatible dermatosis KS. Conclusions. KS not exclusive...

Kaposi sarcoma (KS) is a vascular neoplasm that often manifests with multiple vascular nodules on the skin and other organs. Various imaging modalities can be used to display disease extent. Herein we present a 65-year-old female patient with human immunodeficiency virus negative KS along with her whole-body positron emission tomography/computed tomography imaging findings.

Reported herein is a medical curiosities vascular tumor primary arising from the kidney and exhibiting unique histopathological features. A 32-year-old woman underwent a total nephrectomy of right kidney because of a mass localized in the inferior pole. Distinct from other vascular lesions, on histology the tumor had a peculiar composite pattern, consisting of benign and malignant vascular comp...

patients of all ages and have a reported prevalence rate of 0.001-0.03% in autopsy series and a rate of 0.15% in echocardiac series (1). The majority of primary cardiac tumors are benign. The most common primary cardiac neoplasm is a myxoma, which accounts for approximately half of all cases. Other benign primary tumors include the papillary fibroelastoma, rhabdomyoma, fibroma, hemangioma, para...

BACKGROUND Eccrine poroma is a benign neoplasm that can mimick a malignant neoplasm dermoscopically. The characteristic vascular pattern of this tumor has not been established. OBJECTIVE To evaluate dermoscopic features of non-pigmented eccrine poroma in Mexican patients. METHOD We retrospectively studied histologically proven cases of eccrine poroma from three Mexican hospitals analyzed by...

Pyogenic granuloma (PG) is a benign vascular neoplasm most often evident as a rapidly developing solitary, sessile, or polypoid vascular nodule or tumor prone to ulceration or hemorrhage. Bleeding may be episodic, copious, and refractory to pressure, mandating treatment, particularly when on the lip. We describe a 14-year-old adolescent with a PG of the lower lip that responded to carbon dioxid...

An ulcerated, 1 x 0.5 cm, subcutaneous mass on the craniolateral aspect of the right tibiotarsus of a 4-year-old male cockatiel was removed. Histologically, the neoplasm was non-encapsulated, infiltrative and composed of irregular vascular channels lined by branching and variably sized spindle-shaped cells with large vesicular nuclei, prominent nucleoli and rare mitoses. Surrounding these vascu...

Gliosarcoma is a brain neoplasm that is being recognized with increasing frequency. We discuss the radiographic findings in 14 pathologically proven cases. At angiography in nine cases, four showed mixed dural and pial vascular supply to the lesion. Early cortical venous drainage, irregular tumor vessels, and a prominent vascular stain with well-defined tumor margins were seen in the majority o...
