Sample pathology report. Right thigh, excision: WWTR1-CAMTA1 rearranged epithelioid hemangioendothelioma (see comment) Comment: Tumor is composed of cords and small nests of large endothelial cells with abundant eosinophilic cytoplasm embedded in a myxohyaline stroma. Immunohistochemically, the tumor cells are positive for ERG, CD31, CAMTA1. Infantile hemangiomas (IHs) are the most common tumors of childhood. Unlike other tumors, they have the unique ability to involute after proliferation, often leading primary care providers to assume they will resolve without intervention or consequence. Unfortunately, a subset of IHs rapidly develop complications, resulting in pain, functional impairment, or permanent disfigurement Nomenclature. Our understanding of vascular lesions in infants is markedly hampered by widely varied terminology. The term infantile hemangioendothelioma is generally preferred in the pathology literature to differentiate this neoplasm of infancy from the common benign liver lesion of young adult women widely known as hemangioma (1-3).Others assert that the term hemangioendothelioma leads to. INTRODUCTION. Infantile hepatic hemangioendothelioma (IHH) is a vascular tumor of the liver composed of anastomosing vascular channels lined by plump endothelial cells. 1 It is the most common vascular tumor of the liver in infancy and the third most common hepatic tumor in children. Approximately 85% of affected patients present before 6 months of age, with <5% cases detected beyond 1 year of.

The study comprised 56 girls and 35 boys ranging in age from premature infant to 3 yr; one outlier patient was 18 yr old. Most patients with infantile hemangioendothelioma (87%) were first seen before the age of 6 mo. Congestive heart failure was evident in 15%. Skin hemangiomas were noted in 11% Hemangioendothelioma may refer to: Kaposiform hemangioendothelioma. Epithelioid hemangioendothelioma. Infantile hepatic hemangioendothelioma.

Kaposiform hemangioendothelioma (KHE) is a rare vascular neoplasm typically seen in skin and soft tissue of extremities in infants and children. Although visceral or adult KHE is extremely rare, several cases have been reported. We describe an unusual case of KHE in a 38 year old female who presented with a 2 year history of left upper quadrant. Synonyms: Congenital/infantile hemangiomas. A bright red, elevated lesion results from proliferation of premature capillaries. It appears 3 to 4 weeks after birth, enlarging until the age of 6 to 7 months. The face and arms are often involved. It heals sponta-neously with soft scarring in several years. Dye laser irradiation is the main treatment

Cholangiocarcinomas ( bile duct cancers) are malignant epithelial tumors arising from the biliary tree, excluding the gallbladder or ampulla of Vater. Cholangiocarcinoma is the second most common primary hepatobiliary malignancy after hepatocellular carcinoma (HCC). They tend to have a poor prognosis and high morbidity Simple hepatic cysts may be isolated or multiple and may vary from a few millimeters to several centimeters in diameter. Simple hepatic cysts are benign developmental lesions that do not communicate with the biliary tree 2. The current theory regarding the origin of true hepatic cysts is that they originate from hamartomatous tissue Synovial sarcoma is a cancer that can come from different types of soft tissue, such as muscle or ligaments. One third of patients with synovial sarcoma will be diagnosed under the age of 30. It is somewhat more common in males. Learn more about the tumor, diagnosis, and prognosis from the MyPART project

Hemangioma and hemangioendothelioma. A hemangioma is a primary, benign, frequently symptomatic, vascular neoplasm. Infantile vascular hemangioendothelioma is the most common hepatic mass in the neonate, and over 80% present within the first 6 months of life. Infants typically present with hepatomegaly or are thought to have an abdominal mass Pyogenic granuloma is a common benign vascular tumour occurring in all ages. Both skin and mucous membranes can be affected.

Cavernous hemangioma, also called cavernous angioma, cavernoma, or cerebral cavernous malformation (CCM) (when referring to presence in the brain) is a type of benign vascular tumor or hemangioma, where a collection of dilated blood vessels form a lesion.The abnormal tissue causes a slowing of blood flow through the cavities, or caverns. The blood vessels do not form the necessary junctions. Hemangiosarcoma is a rapidly growing, highly invasive variety of cancer that occurs almost exclusively in dogs, and only rarely in cats, horses, mice, or humans (vinyl chloride toxicity). It is a sarcoma arising from the lining of blood vessels; that is, blood-filled channels and spaces are commonly observed microscopically. A frequent cause of death is the rupturing of this tumor, causing the.

Passive hepatic congestion, also known as congested liver in cardiac disease, describes the stasis of blood in the hepatic parenchyma, due to impaired hepatic venous drainage, which leads to the dilation of central hepatic veins and hepatomegaly..

Hepatic Metastases. The double blood supply of the liver puts it at high risk for metastasis from growths arising in other locations of the body. The porous nature of the sinusoids also allows for easy penetration of malignant cells into the liver. Hepatic Cysts. Fluid-filled sacs in the liver are generally categorized into three types: fibrocystic lesions, cystadenomas and cystadenocarcinomas, and hydatid cysts. The cystic conditions categorized under the fibrocystic diseases of the liver are the following: Simple hepatic cysts. Polycystic liver disease

Kaposiform hemangioendothelioma (KHE)/tufted angioma (TA) Kaposiform hemangioendothelioma was first reported by Zukerberg et al. in 1993 as a Kaposi's sarcoma-like tumor that occurred in infants. KHE has been reported to occur in infants at birth and aged 10 years and younger in many cases, and reports on adult cases have been increasing. Immunohistochemistry: Current Applications in Skin Cancer. Although immunohistochemistry techniques and applications have made great strides in the past 25 years, diagnostics in the world of dermatopathology is still largely based on H&E stained slides. Despite that fact, there are many ways in which immunohistochemistry (IHC) can assist the. Initially, this was thought to possibly be a hemangioendothelioma, a lesion with malignant potential. Eventually however, that diagnosis was excluded.

A pyogenic granuloma or lobular capillary hemangioma is a vascular tumor that occurs on both mucosa and skin, and appears as an overgrowth of tissue due to irritation, physical trauma, or hormonal factors.

HMB-45 is a monoclonal antibody that reacts against an antigen present in melanocytic tumors such as melanomas, and stands for Human Melanoma Black.It is used in anatomic pathology as a marker for such tumors.
