HBME-1 has excellent sensitivity and specificity for the diagnosis of follicular carcinoma.

Superficial dermatomycosis are prevalent pathologies in the medical field and their diagnosis is fundamentally clinical. Histopathology is not considered part of his study, however, the diagnosis is exceptionally obtained by biopsy, when dermatomycosis was not suspected. Unpublished retrospective work is carried out on patients who had the histopathological diagnosis of superficial dermatomycosis between the years 2000-2019 at the HCUCH, based on selection criteria, obtaining 19 patients, in which the following were analyzed: age, gender, clinical characteristics, location, presumptive diagnosis and mycological and histological examinations. He stressed, as was our hypothesis, that dermatomycosis was not clinically suspected, since the presumptive diagnoses were various dermatoses. The most suspected dermatosis was psoriasis, as a result that 57.8% of the dermatoses studied had erythematous scaly plaques on examination. Another relevant fact is that only 21% of the cases underwent a direct mycological prior to the biopsy, which was negative (‘’ false negative’’). It is concluded, then, that superficial dermatomycosis should be considered clinical simulators of other dermatoses, so clinical suspicion and support of mycological examination and fungal culture is essential.

Laryngocele as a differential diagnosis of a thyroid cystA cervical mass is a usual complaint within the clinical practice. Among possible causes, thyroid cysts and nodules are frequent fi ndings. However, there are differential diagnoses that arise from neighboring structures, which can be diffi cult to assess. We report an 18 years old male presenting with a cervical mass, clinically and ecographically suggestive of a right thyroid cyst. Fine needle aspiration was negative for neoplastic cells. Within surgery a paratracheal lesion was identifi ed and resected. The histological fi ndings were compatible with a laryngocele. A laryngocele is an abnormal dilatation of the laryngeal sacule that can simulate a thyroid cyst. Computarized tomography and magnetic resonance are of great importance in its diagnosis, but sometimes is found within surgery or in the anatomopathologic study.Key words: Laryngocele, thyroid cyst, differential diagnosis. ResumenLas masas cervicales son un motivo de consulta usual dentro de la práctica clínica. Dentro de estas, los nódulos y quistes de origen tiroideo son hallazgos frecuentes. Aún así, existen diagnósticos diferenciales originados de estructuras vecinas a la glándula tiroides, cuyo diagnóstico inicial es difícil. Presentamos el caso de un varón de 18 años con una masa cervical derecha, clínica y ecográfi camente sugerente de un quiste tiroideo. La punción-aspiración con aguja fi na fue negativa para células neoplásicas. En el intraoperatorio se identifi có una lesión paratraqueal derecha que fue resecada. El diagnóstico histológico fue compatible con un laringocele. El laringocele es una dilatación anormal del sáculo laríngeo que puede simular un quiste tiroideo. La tomografía computarizada y la resonancia magnética son de gran utilidad en su diagnóstico, pero en ocasiones éste se realiza en el intraoperatorio o mediante el estudio anatomopatológico.Palabras clave: Laringocele, quiste tiroideo, diagnóstico diferencial.
