Résumé :

We report a case of a rare tumor of the head and neck: ectopic hamartomatous thymoma. The tumor involved the sus-clavicular area of a 48 year-old male. Ectopic hamartomatous thymoma exclusively occurs in the sus-scapular region. Histologically, it is characterized by the association of spindle-cell fascicles, epithelial solid or cystic structures and foci of mature adipose tIssue. Spindle cells express diffusely cytokeratins. The differential diagnosis of ectopic hamartomatous thymoma includes mixed tumor of salivary glands, biphasic synovial sarcoma and sarcomatoid carcinoma. Ectopic hamartomatous thymoma is a benign tumor which does not recur after complete excision.
