Retiform hemangioendothelioma: a case series and review of the literature.

J Med Case Rep 2021 Feb 17;15(1):69. Epub 2021 Feb 17.

Department of Pathology and Laboratory Medicine, Aga Khan University Hospital, Karachi, Pakistan.

Background: Retiform Hemangioendothelioma (RH) is an extremely rare vascular tumor of intermediate biological behavior, which is prone to local recurrence but rarely shows metastasis to distant sites. It may harbor areas resembling Dabska tumor in some cases and angiosarcoma, which in its well differentiated form may exhibit similar pathological appearance in some areas, making it problematic to rule out a possibility of a malignant diagnosis on a core biopsy. Therefore, complete surgical resection with negative margins is essential for accurate diagnosis and local control. 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

Morphofunctional basis of the different types of angiogenesis and formation of postnatal angiogenesis-related secondary structures.

Histol Histopathol 2017 Dec 1;32(12):1239-1279. Epub 2017 Aug 1.

Department of Cell Biology and Histology, School of Medicine, Campus of International Excellence, "Campus Mare Nostrum", IMIB-Arrixaca, University of Murcia, Murcia, Spain.

We review the morpho-functional basis of the different types of angiogenesis and report our observations, including the formation of angiogenesis-related secondary structures. First of all, we consider the following issues: a) conceptual differences between angiogenesis and vasculogenesis, b) incidence of angiogenesis in pre- and postnatal life, c) regions of vascular tree with angiogenic capacity, d) cells (endothelial cells, pericytes, CD34+ adventitial stromal cells of the microvasculature and inflammatory cells) and extracellular matrix components involved in angiogenesis, e) events associated with angiogenesis, f) different types of angiogenesis, including sprouting and intussusceptive angiogenesis, and other angiogenic or vascularization forms arising from endothelial precursor cells (postnatal vasculogenesis), vasculogenesis mimicry, vessel co-option and piecemeal angiogenesis. Subsequently, we consider the specific morpho-functional characteristics of each type of angiogenesis. Read More

An unusual mole: an adult case of Dabska tumour.

Coll Antropol 2012 Nov;36 Suppl 2:171-2

Dr. Ivo Pedisić, General Hospital, Department of ENT Surgery, Sisak, Croatia.

In 1969 Dabska and her colleagues described for the first time this rare malignant tumour, also later known as a malignant endovascular papillary angioendothelioma of childhood. Overall, depending amongst other factors on its location, it is thought to have a generally favourable prognosis and a wide local excision seems to be the treatment of choice. We here present a very rare and unusual case of a 63 year old woman with a 20 year history of slow-growing right buccal dermatological lesion which resembled a common mole. Read More

Hemangioendothelioma.

Semin Diagn Pathol 2013 Feb;30(1):29-44

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

Hemangioendothelioma is the term used to name those vascular neoplasms that show a borderline biological behavior, intermediate between entirely benign hemangiomas and highly malignant angiosarcomas. Although originally spindle cell hemangioendothelioma was proposed as a specific clinicopathologic variant of hemangioendothelioma, currently, it is considered as an entirely benign lesion, and thus, the name spindle cell hemangioma seems to be the most accurate for this lesion. Authentic hemangioendotheliomas involving the skin and soft tissues include papillary intralymphatic angioendothelioma (also known as Dabska tumor), retiform hemangioendothelioma, kaposiform hemangioendothelioma, epithelioid hemangioendothelioma, pseudomyogenic hemangioendothelioma (also known as epithelioid sarcoma-like hemangioendothelioma), and composite hemangioendothelioma.

On being a pathologist: Maria Dąbska--the woman behind the eponym, a pioneer in pathology.

Hum Pathol 2011 Jul;42(7):913-7

Dermatology and Pathology, New Jersey Medical School, Newark, NJ 07103, USA.

There is only one cancer to our knowledge named in honor of its female describer, the Dąbska tumor. Maria Dąbska was a brave hero of the Warsaw Resurrection of 1944 who survived deportation to Germany to graduate from medical school in Gdańsk and pursue a career in pathology, for which her research on the Dąbska tumor, breast cancer, sweat gland tumors, keratoacanthoma, soft tissue sarcomas, bone pathology, parachordoma, melanoma, and other entities remains salient. Working behind the Iron Curtain, she nevertheless achieved international recognition, yet few today are cognizant of her and her accomplishments. Read More
