8 patients with cystic carcinoma resembling a lateral cervical cyst by morphology and topography are reported. In 4 cases an analogous carcinoma later appeared in the ipsilateral tonsil, and in 2 tonsillectomized patients subsequent carcinoma developed in the palatopharyngeal arch or at the base of the tongue respectively. One carcinomatous cyst with consecutive involvement of the base of the tongue was preceded by a regular branchiogenic cyst on the opposite side. Removal of a recurrent branchiogenic cyst in another patient revealed unsuspected chronic myeloic leukaemia infiltrating adjacent lymph nodes. The hypotheses regarding the branchiogenic and lymphogenic pathogenesis of such carcinomatous cysts are discussed. Diagnosis should be elaborated as in any carcinomatous lump of the neck and should include serial sectioning of the tonsils and imaging of deep layers. The possibility of synchronous or metachronous tonsillar involvement must always be taken into consideration.
报告了8例形态和位置类似颈侧囊肿的囊性癌患者。4例患者同侧扁桃体随后出现类似的癌，2例扁桃体切除患者分别在腭咽弓或舌根处发生了后续癌。1例癌性囊肿连续累及舌根，之前在对侧有一个正常的鳃源性囊肿。另一名患者复发性鳃源性囊肿切除后发现意外的慢性髓性白血病浸润邻近淋巴结。讨论了关于此类癌性囊肿的鳃源性和淋巴源性发病机制的假说。诊断应像对待颈部任何癌性肿块一样详细，应包括扁桃体连续切片和深层成像。必须始终考虑同步或异时性扁桃体受累的可能性。
