We present a case of a 70 Year-old man with night sweats, weight loss, bilateral leg pain and neuralgia with a single

physical examination finding of bilateral enlarged cervical lymph nodes. He was diagnosed with a rare type of

Langerhans Cell Sarcoma (LCS) mixed with Histiocytic Sarcoma (HS). Both malignancies are hard to diagnose

because they are rare and have non-specific symptoms. Furthermore, HS has similar features as Non-Hodgkin’s

lymphoma and other B-cell Lymphomas. The diagnosis in this case was made by an open biopsy from the left neck,

level IV, which revealed a 19mm hard lymph node without necrosis or adhesions. The pathology showed paracortical

and interfollicular large cell neoplasm, with intermediate/divergent phenotype between HS (Lysozyme+/CD68-

KP1+) and LCS (CD1a+/Langerin+). PET-CT showed a disseminated disease; therefore, the patient was not a

candidate for surgery. In conclusion, although this diagnosis is extremely rare, we should always include it in the

differential diagnosis process of a suspicious cervical lump or mass..
