Carcinoma verrucoso, una variante inusual de tumor laríngeo / Verrucous carcinoma, an unusual variant of laryngeal tumor

Introducción: El carcinoma verrucoso es una variante poco común de carcinoma escamoso bien diferenciado, que carece de rasgos citológicos de malignidad, tiene un crecimiento lento, es infiltrativo, pero no metastatiza. Objetivo: Identificar los aspectos clínico-histopatológicos y terapéuticos de una variante inusual de tumor laríngeo. Presentación del caso: Se reporta un nuevo caso de carcinoma verrucoso, paciente masculino de 78 años que se presentó en la consulta de Otorrinolaringología del Hospital Docente general "Enrique Cabrera" con disfonía. Se realizó laringoscopia indirecta y se detectó lesión exofítica sugestiva de neoplasia. Se tomaron tres biopsias, solo la última, fue de utilidad para diagnosticar un carcinoma verrucoso. Se trató con radiaciones y cirugía. El paciente presenta un intervalo libre de enfermedad después de ocho años de seguimiento. Conclusiones: Para el diagnóstico del carcinoma verrucoso es necesario biopsias profundas y la acuciosidad del patólogo para llegar al diagnóstico. Se hace énfasis en la importancia del trabajo en el contexto del grupo multidisciplinario(AU)

Introduction: Verrucous carcinoma is an uncommon variant of a well differentiated squamous carcinoma that lacks cytological features of malignancy and is often slow-growing, infiltrative, but not metastatic. Objective: To identify the clinical, histopathologic and therapeutic aspects of an unusual variant of laryngeal tumor. Case presentation: A 78-year-old male patient who attended the otorhinolaryngology consultation at "Enrique Cabrera" General Teaching Hospital with dysphonia is reported as a new case of Verrucous carcinoma. Indirect laryngoscopy was performed and an exophytic lesion suggestive of neoplasia was detected. Three biopsies were taken, but only the last one was useful to diagnose a Verrucous carcinoma. It was treated with radiation and surgery. The patient has a disease-free survival after eight years of follow-up. Conclusions: Deep biopsies performed by a skillful pathologist are necessary to reach the diagnosis of Verrucous carcinoma. Emphasis is placed on the importance of working in the context of a multidisciplinary team(AU)

Amigdalitis hemorrágica como presentación de Sarcoma de Kaposi / Hemorrhagic tonsillitis as a presentation of Kaposi's sarcoma

Introducción: Las lesiones en la cavidad oral son con frecuencia las primeras evidencias clínicas de la infección por VIH. Una amigdalitis hemorrágica debe hacer sospechar, entre otras causas, que exista un Sarcoma de Kaposi (SK). El SK, considerada una enfermedad marcadora de sida en la infección por VIH, afecta, fundamentalmente, la piel y con frecuencia la mucosa de la cavidad oral. Objetivo: identificar una amigdalitis hemorrágica como forma de presentación de un Sarcoma de Kaposi asociado al VIH Presentación del caso: Paciente masculino de 22 años, que consulta por odinofagia y disfagia. En la faringoscopìa se observan amígdalas hipertróficas y de aspecto hemorrágicas. Se sospecha causa sistémica, entre ellas la infección por VIH. Se confirma debut clínico de sida por SK con lesiones predominantes de cavidad oral incluyendo las amígdalas. Conclusiones: Las características hemorrágicas de una amigdalitis permitieron sospechar el diagnóstico infección por VIH con Sarcoma de Kaposi predominante en cavidad oral(AU)

Introduction: Lesions in the oral cavity can be the first clinical evidences of HIV infection. Hemorrhagic tonsillitis should be suspicious of a Kaposi's sarcoma, among other causes. Kaposi's sarcoma (KS) is considered a marker of AIDS in HIV infection, which mainly affects the skin, but often acts upon the mucosa of the oral cavity. Objective: To identify hemorrhagic tonsillitis as a form of presentation of Kaposi's sarcoma associated to HIV. Case presentation: A 22-year-old male patient comes to the doctor´s office complaining of odynophagia and dysphagia. Hypertrophic tonsils of hemorrhagic aspect are observed in the laryngoscopy. Systemic cause is suspected, mainly, an HIV infection. A clinical onset of AIDS as a result of KS with predominant lesions in the oral cavity including the tonsils is confirmed. Conclusions: The hemorrhagic characteristics of tonsillitis leads to a presumptive diagnostic of HIV infection with a Kaposi's sarcoma occurring predominantly in the oral cavity(AU)

Hyaline globules and papillary fragments in cytologic smears from two intra-abdominal tumors (ovarian and hepatic) in female patients: A diagnostic pitfall with histologic correlation.

Hyaline globules and papillary fragments in cytologic samples from two intra-abdominal tumors in young females are presented including the cytological features and the correlation with the histopathologic and immunohistochemical findings. In the first case a cytologic study from an ovarian mass showed papillary structures and isolated tumor cells with epithelioid morphology, irregular reniform-like nuclear contour, pale or vacuolated cytoplasm, abundant hyaline globules and occasional glomeruloid structures resembling Schiller-Duval bodies. Yolk sac tumor (YST) was the diagnosis on the histological slides. Tumor cells showed positivity for cytokeratin (AE1/AE3), epithelial membrane antigen (EMA), alpha-fetoprotein (AFP) and Sal-like protein 4 (SALL4). In case number two the cytologic study from a liver metastasis displayed papillary and rosette-like clusters composed of uniform and bland cells showing occasional long cytoplasmic tails, hyaline globules and nuclear grooves. A diagnosis of hepatic metastasis from solid pseudopapillary neoplasm of the pancreas (SPNP) was rendered from the histology. Tumor cells revealed immunoreactivity for cytokeratin (AE1/AE3), Vimentin, Galectin-1 (GAL-1), Neuron specific-enolase, CD10, progesterone and ß-catenin (nuclear stain). Regarding differential diagnosis, in the patient with the ovarian mass an ovarian clear cell carcinoma was considered, as well as other germ cell tumors or metastatic carcinoma, while in the patient with a liver metastasis a neuroendocrine carcinoma was taken into account. YST and SPNP share some cytological findings, including hyaline globules, papillary structures, clear cells and intercellular eosinophilic basement membrane deposits. Thus, a detailed study and careful interpretation of the cytological, histological and immunohistochemical findings may be worthwhile to avoid a potential misdiagnosis, particularly in the cytologic specimens of the ovarian and/or intra-abdominal mass, when involving young females.
