Metastatic Carcinoma to Vertebra Mimicking as Primary Malignant Vascular Tumour; A unusual Case Report

Excerpt

Papillary intralymphatic angioendothelioma (PILA) or Dabska tumor is an extremely rare vascular tumor. It is discovered by Maria Dabska and only 33 cases have been reported till date [1]. It usually occurs in infants and children although 25 % of the cases occur in adulthood [2]. Most of these occur in the dermis and subcutaneous tissue of extremities [3]. Other locations include spleen, tongue, testis and bone. Intraosseous PILA is very rare and only three cases have been reported. They present as plaques or nodules with asymptomatic growth until it reaches significant size [1, 2]. This lesion present as osteolytic lesion [1, 4, 5]. Surgical excision is the treatment [3, 4]. Histopathology shows interconnecting vascular channels lined by mildly atypical cuboidal endothelial cells with hob nailing and small papillary tufts into lumen [1, 2]. Prognosis is excellent with complete wide excision [1]. We present a case of 42 year old male who came with complains of neck pain of 2 months duration. Lesional biopsy showed metastatic carcinoma with features closely mimicking dabska tumor and which was later confirmed by immunohistochemistry. …
