Targetoid Hemosiderotic Hemangioma With Spontaneous Remission and Recurrence in a Male Patient: A Case Report

Targetoid hemosiderotic hemangioma is a rare, characteristic, benign lymphovascular lesion that usually affects the trunk and lower limbs. It has a diverse clinical appearance. Most affected people are in their 20s. A violaceous solitary papule encircled by a pale, narrow region and an ecchymotic ring peripherally, mimicking a target, is the most prevalent clinical characteristic. In many cases, the reported dermoscopic signs and patterns of hemosiderotic hemangioma have been found to be adequate for establishing a clinical diagnosis. The following is a case of a 23-year-old male presenting with blue-black vascular lesions on the lateral aspect of the right deltoid with a red ecchymotic ring. The 2×1 cm-sized lesion has a history of spontaneous remission and reappearance. Based on dermoscopic findings, a diagnosis of targetoid hemosiderotic hemangioma was made.

Orbital Hobnail Hemangioma

A 64-year-old woman presented with a 1 year history of progressive left proptosis and "blurry vision." Imaging studies revealed a left superior orbital mass distorting the optic nerve and superior rectus muscle. Excisional biopsy established the diagnosis of hobnail hemangioma. This report describes the first case of an orbital hobnail hemangioma, a lesion that more commonly presents in the dermis.

High-Fat Diet and Alcohol Intake Promotes Inflammation and Impairs Skin Wound Healing in Wistar Rats

The wound-healing process is complex and remains a challenging process under the influence of several factors, including eating habits. As improper diets may lead to disorders such as dyslipidemia, insulin resistance, and chronic inflammation, potentially affecting the tissue ability to heal, we decided to investigate the effect of a high-fat diet and alcohol intake on the inflammatory process and skin wound healing in Wistar rats. Male rats (n = 30) were individually housed in cages with food and water ad libitum (registration number 213/2014). After anesthesia, at day 40, three circular wounds (12 mm diameter) were made on the back of each animal, which were then randomly assorted into five treatment groups: C1 (control 1)-water via gavage and standard chow diet; C2 (control 2)-water (no gavage) and standard chow diet; AL (alcohol)-water (no gavage) and alcohol (40%) via gavage and standard chow diet; HF (high fat)-water (no gavage) and high-fat diet (50%); and HF + AL (alcohol/high fat)-water (no gavage), alcohol (40%) via gavage, and high-fat diet. Animals were treated for 61 days. Every seven days, the area and the rate of wound contraction were evaluated. Tissue samples were removed for histopathological analysis and biochemical analyses. Our results showed that wound contraction was not complete in the HF + AL rats. Two specific indices of wound-healing impairment (total cell number and levels of the inflammatory cytokine TGF-β) were increased in the HF + AL rats. We also observed decreased type I and III collagen fibers in the HF, AL, and HF + AL groups and increased oxidative stress markers in the same groups. We suggest that a high-fat diet combined with alcohol intake contributed to delayed skin wound healing through increase of the inflammatory phase and promoting oxidative stress, which may have led to morphological alterations and impaired matrix remodeling.

Composite Hemangioendothelioma: Report of a Rare Case

Composite Hemangioendothelioma (CHE) is a new entity classified under the Heman gioendothelioma (HE) group of tumours. It is an extremely rare vascular neoplasm of low to moderate malignancy. Very few cases have been described in the literature. We herein report a case of CHE arising in a 31-year-old male who presented with a history of painless slow growing swelling on upper back since 1year. Clinically, the surface of firm and mobile swelling of 1.5x1.5cm showed focal ulcerations. The histopathological findings were consistent with the diagnosis of composite hemangioendothelioma. The patient underwent wide local excision and at the end of five months of follow up there were no features of local recurrence or metastasis. To the best of our knowledge, this is the first reported case of CHE from India.
