Diffuse dermal angiomatosis of the breast: an emerging entity in the setting of cutaneous reactive angiomatoses.

Clin Dermatol 2021 Mar-Apr;39(2):271-277. Epub 2020 Oct 16.

Unit of Dermatology, Department of Medical Sciences and Public Health, Dermatology Clinic, University of Cagliari, Cagliari, Italy.

New and emerging types of cutaneous vascular (capillary) proliferations have been described or better categorized in the last few years. They include reactive angioendotheliomatosis, acroangiodermatitis (pseudo-Kaposi sarcoma), diffuse dermal angiomatosis, intravascular histiocytosis, glomeruloid angioendotheliomatosis, and angiopericytomatosis (angiomatosis with cryoproteins). Clinically, they are characterized by multiple, red violaceous, and purpuric patches and plaques, sometimes evolving toward necrosis and ulceration with a wide distribution but a propensity to involve the extremities.

Vet Pathol 2021 09 11;58(5):864-880. Epub 2020 Dec 11.

5922Cornell University, Ithaca, NY, USA.

In disease, blood vessel proliferation has many salient roles including in inflammation, when granulation tissue fills superficial defects, or in the recanalization of an occluded blood vessel. Sometimes angiogenesis goes awry-granulation can be exuberant, and plexiform proliferation of vascular components can contribute to pulmonary hypertension. This review focuses on the diverse manifestations of pathologic vascular overgrowth that occur in the brain, spinal cord, and meninges of animals from birth until old age. Read More

Intravascular Cutaneous Disorders. A Clinicopathologic Review.

Am J Dermatopathol 2021 Feb;43(2):119-136

Department of Dermatology, Fundación Jiménez Díaz, Universidad Autónoma, Madrid, Spain; and.

Abstract: Intravascular proliferations of the skin are clinically heterogeneous and may present with a wide range of clinical features, including violaceous papules, nodules, plaques, or other unspecific cutaneous lesions. Histopathologically, these conditions are characterized by proliferation of different cell types within the lumina of dermal vessels and endothelial cell hyperplasia. Immunohistochemistry is the best tool to identify the nature of the intravascular proliferating cells and the type of involved vessel. Read More

Painful tumors of the skin: "CALM HOG FLED PEN AND GETS BACK".

Clin Cosmet Investig Dermatol 2019 13;12:123-132. Epub 2019 Feb 13.

Compass Dermatopathology, San Diego, CA, USA.

Painful tumors of the skin present as dermal or subcutaneous nodules. They can originate from several sources: adipose tissue, cartilage degeneration, deposition of bone or calcium, eccrine glands, fibrous tissue, infiltration of benign (endometrium) or malignant (metastatic neoplasm) tissue, muscle, nerve, or vascular structures. Although pathologic evaluation of the lesion is necessary to determine the diagnosis, it is possible to make a reasonable differential diagnosis based on knowledge of prior tumors that have appeared as tender lesions.

Differentiating Intralymphatic Histiocytosis, Intravascular Histiocytosis, and Subtypes of Reactive Angioendotheliomatosis: Review of Clinical and Histologic Features of All Cases Reported to Date.

Am J Dermatopathol 2017 Jan;39(1):33-39

*Virginia Tech Carilion Dermatology and Mohs Surgery, Roanoke, VA; and †Cleveland Clinic, Dermatology and Plastic Surgery Institute, Cleveland, OH.

Reactive angioendotheliomatosis (REA) is a rare benign angioproliferative condition of the skin, which has been noted to occur in patients with a variety of underlying systemic diseases. Histopathologically, this condition is characterized by vascular proliferation, and endothelial cell hyperplasia within the lumina and around dermal vessels, without significant cellular atypia. Since the first case of RAE was reported in 1958, multiple histologic patterns of benign cutaneous vascular proliferations with similar clinical presentations to RAE have been described in the literature and have been proposed as subtypes of the originally described condition.

Anatomical Pathology Department, Marqués de Valdecilla University Hospital, Medical Faculty, University of Cantabria and IDIVAL, Santander, Spain.

Intravascular histiocytosis (IVH) is a rare condition of uncertain pathogenesis often associated with rheumatoid arthritis (RA) exclusively observed in the skin. In a retrospective study of 207 consecutive cases of aortic valve disease, we observed two cases of IVH characterized by the presence of thin-walled, dilated blood vessels containing collections of CD68+ and CD163+ mononuclear histiocytes. Immunostains for CD31, CD34, and D2-40 confirmed the intravascular location of these histiocytes. Read More
