    Intraosseous papillary intralymphatic angioendothelioma (PILA): one new case and review of the literature.
    Clin Sarcoma Res 2018 30;8. Epub 2018 Jan 30.
    1Department of Pathology, Rizzoli Institute, Bologna, Italy.
    Background: Papillary intralymphatic angioendothelioma (PILA) is a locally aggressive, rarely metastasizing vascular tumor, generally occurring in the soft tissues, with less than 40 cases described in the literature and only three cases reported in bone.

    Case Presentation: We describe the case of a 51-year-old male with an intraosseous PILA of the proximal edge of his left clavicle and two other lesions evident on imaging. The patient was treated with marginal resection of the clavicle lesion but was lost to follow-up 1 month after surgery. 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

    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

There have been only 33 reports on malignant transformation of a benign eccrine spiradenoma since the first description by Dabska in 1972. Most cases have originated on a long-standing cutaneous lesion. Read More

    The Dabska tumor: a thirty-year retrospect.
    Dermatology 2000 ;201(1):1-5
    Dermatology and Pathology, New Jersey Medical School, Newark, N.J., and Pathology, State University of New York at Buffalo School of Medicine, Buffalo, N.Y., USA.
    The Dabska tumor is a rare low-grade angiosarcoma also known as malignant endovascular papillary angioendothelioma of childhood. It primarily affects the skin of children and has a distinctive histologic pattern of anastomosing vascular channels with intravascular papillary outpouchings projecting, sometimes, in a glomerulus-like pattern, into a lumen lined by atypical columnar endothelial cells. Since its original description 30 years ago by one of us, knowledge in this area has expanded. Read More

    Vascular endothelial growth factor receptor-3 (VEGFR-3): a marker of vascular tumors with presumed lymphatic differentiation, including Kaposi's sarcoma, kaposiform and Dabska-type hemangioendotheliomas, and a subset of angiosarcomas.
    Mod Pathol 2000 Feb;13(2):180-5
    Department of Pathology, Emory University, Atlanta, Georgia, USA.
    Recently, a novel monoclonal antibody to vascular endothelial growth factor receptor 3 (VEGFR-3), a tyrosine kinase receptor expressed almost exclusively by lymphatic endothelium in the adult, has been shown to react with a small number of cases of Kaposi's sarcoma (KS) and cutaneous lymphangiomas. We sought to extend these studies to a large number of well-characterized vascular neoplasms to evaluate diagnostic uses of this antibody and to determine whether it defines them in a thematic fashion. Formalin-fixed, paraffin-embedded sections from 70 vascular tumors were immunostained with antibodies to VEGFR-3 von Willebrand factor (vWF), and CD31. Read More

    Endovascular papillary angioendothelioma (Dabska tumor)
    Pathol Int 1998 Oct;48(10):840-1
    The histological diagnosis of endovascular papillary angioendothelioma (EPA) (Dabska tumor) is controversial although the tumor is included in the World Health Organization classification. Papillary endothelial proliferation with a central hyaline core is one of the most characteristic features of EPA; however, this type of proliferation has been observed in other vascular tumors, such as angiosarcoma, retiform hemangioendothelioma and glomeruloid hemangioma. Several vascular tumors have EPA-like foci and EPA is not well defined generally. Read More

    Malignant endovascular papillary angioendothelioma (Dabska tumor). A case report and review of the literature.
    Am J Dermatopathol 1989 Feb;11(1):64-8
    Department of Pathology, Mount Sinai Medical Center of Greater Miami, Florida 33140.
    Malignant endovascular papillary angioendothelioma is a rare vascular tumor of childhood that was first defined by Dabska in 1969. Microscopically, this tumor is composed of anastomosing vascular channels, some of which contain papillary projections or tuft-like structures sometimes resembling renal glomeruli. Although cases have been reported with metastases to regional lymph nodes, the long term prognosis for patients with these tumors is generally good. Read More

    Mesenchymal chondrosarcoma. A clinicopathologic analysis of 35 patients with emphasis on treatment.
    Cancer 1983 Apr;51(7):1230-7
    Almost a quarter of a century has passed since mesenchymal chondrosarcoma, a rare, insufficiently studied and still poorly understood cartilage neoplasm has been described. Based on 35 cases diagnosed and treated at this Cancer Center, this study found 20 males and 15 females with an average age of 26 years (range, 6-70 years). All but five of the tumors arose in the skeleton in the femur, humerus, and ilium in five cases each, while the os calcis (a rare site for any other osseous tumor) gave rise to this tumor in four instances.

    Decrease of mast cells in the stroma of human cancer.
    Arch Immunol Ther Exp (Warsz) 1983 ;31(2):261-6
    The number of mast cells in the stroma of human squamous cell cancer -- keratoblastif cum, paraepidermale and male diffusa was 2-30 times lower than in the stroma o-normal squamous epithelium or in the connective tissue distant from neoplastic epithelium. These differences are statistically highly significant. The reduction of mast cel, number apparently might be the result of exhaustion of heparin-containing granules which interfere with tumor growth. Read More
