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.

Retiform hemangioendothelioma: A case report and literature review.

Introduction And Importance: Retiform hemangioendothelioma(RH) is a rare vascular tumor affecting patients over a wide age range without a gender predilection; only about 50 cases have been described so far.
Case Presentation: We report a case of submandibular retiform hemangioendothelioma in a 58-year-old woman who had been diagnosed with RH 20 years ago and had experienced recurrence four times during the past 20 years. This will increase the limited number of such cases in the hope of gaining a better understanding of this rare type of tumor.

Article Synopsis
- Targetoid hemosiderotic hemangioma (THH) is a rare vascular lesion that mainly affects adults, usually developing after trauma, with no significant gender preference.
- The review analyzes THH's characteristics, differentiating it from similar conditions like Kaposi's sarcoma and retiform hemangioendothelioma.
- Clinically, THH appears as painless lesions with a distinctive target-like look; histologically, it shows specific vascular features and can be identified with immunohistochemical markers.

Epithelioid hemangioma (EH) is a rare angioproliferative disorder for which histopathology is the main approach to diagnosis. The tendency to recur is of concern to clinicians and patients. The factors associated with recurrence have been sporadically reported and a large-scale cohort study has been lacking.

Article Synopsis
- Thrombotic hemangioma with organizing/anastomosing features (THOA) is a newly recognized variant of hemangioma linked to mutations in GNA genes, displaying unique clinical and morphological traits.
- Although it shows benign behavior, histological features may cause concerns for a low-grade malignant vascular neoplasm.
- A case study of a 74-year-old woman revealed persistent THOA through next-generation sequencing, identifying specific gene mutations and contributing to understanding the lesion's characteristics and prognosis.
Evaluation of PRAME immunohistochemistry in cutaneous vascular neoplasms reveals frequent expression in primary and post-irradiation cutaneous angiosarcomas.

Department of Pathology and Laboratory Medicine, Cedars-Sinai Medical Center, Los Angeles, California, USA.
Background: Preferentially expressed antigen in melanoma (PRAME) has been extensively studied in cutaneous melanocytic tumors and has proven valuable as a diagnostic adjunct in routine dermatopathology practice. However, its expression in cutaneous vascular neoplasms, particularly angiosarcomas (AS), remains largely unexplored.
Methods: To further explore PRAME expression in cutaneous AS, 18 cases of post-irradiation and 13 cases of primary cutaneous AS were evaluated for PRAME.
