Hemangioendotheliomas are a family of vascular neoplasms of intermediate malignancy. Signs and symptoms
They have been described as masses that fall between a hemangioma and angiosarcoma. They are vascular tumors that commonly present with an enlarging mass and most commonly involve the lungs, liver, and musculoskeletal system, although many other body sites have been reported, including the head and neck, intestines, lymph nodes, pleura, retroperitoneum, heel, stomach. Cause
Possibly Bartonella spp bacteraemia

Diagnosis
Classification
Hemangioendotheliomas may be classified as:

Epithelioid hemangioendothelioma is an uncommon vascular tumor of intermediate malignancy that was first described by Steven Billings, Andrew Folpe, and Sharon Weiss in 2003. These tumors are so named because their histologic appearance resembles a proliferation of epithelioid cells, with polygonal shape and eosinophilic cytoplasm. Composite hemangioendothelioma is a low-grade angiosarcoma typically occurring in adults, although it has been described in infancy. : 601 
Spindle-cell hemangioendothelioma) is a vascular tumor that was first described in 1986 by Sharon Weiss, M.D., and commonly presents in a child or young adult who develops blue nodules of firm consistency on a distal extremity. : 599  These tumors were reclassified by Dr. Weiss in 1996 as "spindle cell hemangioma", rather than hemangioendothelioma, due to the excellent prognosis observed in a group of 78 patients. Retiform hemangioendothelioma (also known as a "Hobnail hemangioendothelioma") is a low-grade angiosarcoma, first described in 1994, presenting as a slow-growing exophytic mass, dermal plaque, or subcutaneous nodule. : 601 
Kaposiform hemangioendothelioma (also known as "Infantile kaposiform hemangioendothelioma") is an uncommon vascular tumor, first described by Niedt, Greco, et al.
Desoximetasone is a medication belonging to the family of medications known as topical corticosteroids. It is used for the relief of various skin conditions, including rashes. It helps to reduce redness, itching, and irritation. Desoximetasone is a synthetic corticosteroid, a class of primarily synthetic steroids used as anti-inflammatory  and anti-pruritic  agents. Three brand name products are available (availability depending on country):

Topicort Emollient Cream (0.25% desoximetasone)
Topicort LP Emollient Cream  (0.05% desoximetasone)
Topisolone Cream  (0.25% desoximetasone)

Usage
When using desoximetasone, some of the medication may be absorbed through the skin and into the bloodstream. Too much absorption can lead to unwanted side effects elsewhere in the body. Large amounts of desoximetasone should be avoided over large areas. It should not be used for extended periods of time. Treated areas should not be covered with airtight dressings such as plastic wrap or adhesive bandages. Children may absorb more medication than adults do. Desoximetasone is for use only on the skin and should be kept out of the eyes. Desoximetasone can also be used to treat some types of psoriasis. See also
Clobetasol propionate
Dexamethasone
