Follicular thyroid carcinoma is known to metastasize to distant places even before the primary follicular thyroid carcinoma is clinically obvious. One such unusual and distant metastasis of follicular thyroid carcinoma is its subcutaneous location. The present case report is an unusual one. A 50-year-old man with a history of trauma on the scalp developed non resolving hematoma. The swelling was soft with greenish discolouration to the skin over it. The swelling was soft with greenish discolouration to the skin over it. The Fine Needle Aspiration Cytology (FNAC) of the swelling revealed the classic cytomorphology of metastatic follicular thyroid carcinoma. The clinical examination of thyroid was normal at this juncture cytodiagnosis. The USG of the thyroid showed a deeply placed nodule of higher Thyroid Imaging Reporting & Data System (TIRAD). The FNAC from this nodule was also performed. The diagnosis of follicular neoplasm favoring follicular thyroid carcinoma was offered. The patient underwent thyroidectomy. The histological examination of tumor tissue was consistent with the diagnosis of thyroid follicular carcinoma. This case offers a unique insight into the non-resolving hematoma harboring the metastatic lesion of follicular thyroid carcinoma in the patient with the silent primary in the thyroid.
已知滤泡状甲状腺癌甚至在原发性滤泡状甲状腺癌出现临床症状之前就会发生远处转移。滤泡状甲状腺癌一种不寻常的远处转移是其皮下转移。本病例报告很不寻常。一名50岁男性，有头皮外伤史，头皮血肿经久不愈。肿胀处质地柔软，上方皮肤呈绿色。对肿胀处进行细针穿刺抽吸细胞学检查（FNAC），结果显示为转移性滤泡状甲状腺癌的典型细胞形态。此时甲状腺临床检查正常，进行了细胞诊断。甲状腺超声检查显示有一个位于深部的、甲状腺影像报告和数据系统（TIRAD）分级较高的结节。也对该结节进行了FNAC。结果提示为倾向于滤泡状甲状腺癌的滤泡性肿瘤。患者接受了甲状腺切除术。肿瘤组织的组织学检查结果与甲状腺滤泡状癌的诊断相符。该病例为甲状腺隐匿性原发癌患者中，非愈合性血肿内藏有滤泡状甲状腺癌转移灶提供了独特的见解。
