INTRODUCTIONThe deep cervical lymph nodes are regarded as the drainage lymphatics of the head and neck region. Head and neck malignancies often present as firm, solid nodal masses. However, malignancies arising from Waldeyer's Ring may give rise to cystic lymph nodes.We report a case of pigmented epithelioid melanocytoma with nodal melanosis in a patient who presented with cystic cervical lymphadenopathy.CASE REPORTA 57‐year‐old man was referred for a left‐sided neck swelling of 2 weeks' duration. Examination showed a 2.5‐cm smooth firm left supraclavicular lymph node.

He underwent excision biopsy during which a 2.5‐ × 2.5‐cm nodule containing blackish fluid was found. Histology reported nodal fibrosis with melanophages (see Figure ). Immunostaining for SOX10, S100, and Melan A were negative; no melanocytes were detected.A CT scan of the neck revealed an enlarged cystic cervical node at level 5A/BNodal fibrosis with numerous melanophages (original magnification × 20)Subsequent dermatological examination unveiled a 0.8‐cm black nodule on his upper back (see Figure ).
