Intravenous Lobular Capillary Hemangioma: A Case Report and Proposal for New Cutaneous Tender Tumor Differential Diagnosis Acronym.

Here, we report a case of a 70-year-old female who presented with a slowly enlarging tender nodule on the right forearm for several months. Physical examination showed a faintly blue-tinged freely mobile subcutaneous nodule. Excision was complicated by greater than expected bleeding and revealed an unexpected intravenous mass. Histopathology demonstrated capillary lobules separated by fibrous septae within a vein, consistent with intravenous lobular capillary hemangioma (IVLCH). IVLCH is a rare benign capillary proliferation of unclear etiology. Excision is typically curative and relieves any pain and discomfort the patient might be experiencing. With the addition of IVLCH, we respectfully propose a new acronym for the differential diagnosis of cutaneous tender tumors: intravenous lobular capillary hemangioma, foreign body (reaction), hidradenoma, osteoma cutis, glomus tumor, scar, fibromyxoma, leiomyosarcoma, eccrine angiomatous hamartoma, Dercum's disease (adiposis dolorosa), piezogenic pedal papule, eccrine spiradenoma, neurilemmoma (schwannoma), calcinosis cutis, angioendotheliomatosis, leiomyoma, metastases, angiolipoma, neuroma, dermatofibroma, granular cell tumor, endometriosis, thrombus, blue rubber bleb nevus, angioma, chondrodermatitis nodularis helicis, and keloid ("IF HOGS FLED PEN, CALM AND GET BACK"). Future additions to the cutaneous tender tumor differential diagnosis may require creative additions and rearrangements to this acronym. However, continual updates will allow it to serve both clinicians and pathologists alike as a comprehensive representation of etiologies to consider for cutaneous tender tumors.
