Dear Editor,
Primary benign vascular tumors of lymph node are very rare. Less than 60 cases are reported in literature.[1],[2] We report case of primary lymph node hemangioma in a 67-year-old lady who presented with an asymptomatic axillary swelling.
She visited our hospital for evaluation of left axillary swelling which she had noticed about 2 weeks back. Clinical examination revealed a firm, non-tender mobile swelling in the left axilla. Ultrasound of the left breast detected an isoechoic well-circumscribed mobile lesion in the left axillary region measuring 2.8 × 2.3 cm. The left breast was normal. CT thorax with contrast also showed an enlarged left axillary lymph node [Figure 1]a. No abnormalities were detected elsewhere in the chest. Fine-needle aspiration cytology attempted yielded only blood. Excision of the axillary swelling was done. The gross specimen was an encapsulated nodular mass measuring 2 × 1.5 × 1 cm. The surface showed attached fatty tissue. Cut section of mass had a grey-brown appearance [Figure 1]b. Microscopic evaluation revealed a well-encapsulated nodular mass composed of capillary vessels [Figure 2]a. Most of the nodal parenchyma was replaced by the vascular neoplasm except for little residual lymphoid tissue beneath the capsule [Figure 2]b. The capillaries showed hob nailing of endothelial cells in some areas [Figure 2]c. There was no increase in mitosis or nuclear atypia. The endothelial cells lining the capillaries are positive for CD34 [Figure 2]d. | Figure 1: (a). CT chest showing left axillary lymphadenopathy. (b). Gross specimen of excised axillary lymph node

Hemangiomas of lymph nodes may be capillary, cavernous, or mixed.[3] There appears to be a female predominance, and usually, only a single node tends to be involved.[2],[4] Some are detected incidentally along with radical resection specimens or present as mass lesions.[4],[5] Differential diagnoses are other types of vascular tumors, benign ones including angiomyomatous hamartoma and lymphangioma, and malignant ones including hemangioendothelioma, Kaposi sarcoma, and angiosarcoma. Angiomyomatous hamartoma is seen only in inguinal lymph nodes. The parenchyma is replaced by blood vessels, fat, smooth muscle, and fibrous tissue without cellular fascicle formation. Lymphangioma consists of uncircumscribed small spaces filled with a proteinaceous material and floating lymphocytes and lined by a flat endothelial layer. The absence of atypia and mitosis rule out malignant vascular tumors. Vascular transformation of the sinus shows vascular proliferation restricted to sinuses, occasionally associated with obstruction.[3],[4] Benign vascular tumors of lymph nodes are less common than either non-neoplastic vascular hyperplasia or malignant lesions. They are usually incidental findings with no clinical significance. Surgical excision is curative in primary nodal hemangioma. Some cases that have been followed-up did not show any recurrences.[4] However, it is important to recognize them to avoid a misdiagnosis of malignant lesions or metastasis. To conclude, the authors present an extremely rare vascular lesion of the lymph node.
