%X Chondrosarcoma is the third most frequently occurring bone tumor, following myeloma and osteosarcoma; it accounts for around 20% of all malign bone tumors. They are usually localized in the long bones and the bones of the pelvis; only 2% to 5% are located in the head and neck, mainly in the maxillary bone. Initial symptoms are usually very bizarre and sometimes only a sensation of having a neck mass means that a patient goes to see a doctor. Due to the larynx's intimate relationship with the thyroid gland, this tumor may give a false diagnostic impression. As happened in this case, a patient consulted due to level 4 mass (central neck area), echography of the thyroid nodule and fine needle aspiration (FNA) having proved positive for thyroid goiter. The presence of an invasive thyroid carcinoma was suspected in the TAC due to infiltration of the cricoid cartilage; a well-differentiated diagnosis of chondrosarcoma (grade 1) was only made during surgical intervention orientated by biopsy following intraoperation exposure and the definitive study of the pathology. This case has been reported and the topic reviewed as it was difficult case to diagnose and involved a very infrequently occurring pathology. El condrosarcoma es el tercer tumor m芍s frecuente de los huesos, luego del mieloma y el osteosarcoma, y constituye aproximadamente el 20% de todos los tumores 車seos malignos. Generalmente se localiza en los huesos largos y de la pelvis y tan s車lo 2 a 5% se ubican en la cabeza y el cuello, principalmente en el maxilar. Los s赤ntomas iniciales suelen ser muy bizarros y en ocasiones s車lo la sensaci車n de masa del cuello hace que el paciente acuda al m谷dico. Por la 赤ntima relaci車n de la laringe y de la gl芍ndula tiroides, este tumor puede llevar a una falsa impresi車n diagn車stica. Como ocurri車 en este caso, una paciente que consult車 por masa del nivel VI (zona central del cuello), con ecograf赤a de n車dulo tiroideo y aspiraci車n con aguja fina (ACAF) positiva para un bocio tiroideo. En la TAC por infiltraci車n del cricoides se sospech車 la presencia de un carcinoma tiroideo invasivo, y s車lo hasta la intervenci車n quir orgica en orientaci車n con la biopsia por congelaci車n intraoperatoria y el estudio definitivo de patolog赤a se realiz車 el diagn車stico de condrosarcoma bien diferenciado (Grado 1). Como es un caso de dif赤cil diagn車stico y una patolog赤a muy infrecuente se report車 y se revis車 el tema.
