[Cervical cystic metastasis in ENT carcinoma. Differential diagnosis with the branchioma]. / Metástasis quística cervical en carcinomas O.R.L. diagnóstico diferencial con el tumor branquiogénico.

This study report 3 cases of nodal cystic metastasis in the neck. One of them was diagnosed as an epidermoid carcinoma of unknown origin and the other 2 were an epidermoid carcinoma and an mucoepidermoid carcinoma respectively, arising in the larynx. Treatment of these patients included removal of the cystic metastasis with or without neck dissection and irradiation. Cystic metastasis from squamous cell carcinoma have often been mistaken for primary squamous cell carcinoma of branchiogenic origin. The distinctive histological features of cystic metastasis reviewed after its correct identification, can lead to the discovery of an unsuspected primary lesion and result in specific treatment options.

[Histopathological aspects of the benign lymphoreticulosis, cat scratch disease, or cervical localization]. / Aspectos histopatológicos de la linforreticulosis benigna o enfermedad por arañazo de gato de localización cervical.

Report about 2 children affected with the cat scratch disease or lymphoreticulosis. The AA. discuss some etiological and clinic features of the malady, especially emphasizing the typical anatomopathological findings, which in the majority of the occurrences, allow the actual diagnosis. This is a disease of low incidence, but must be bear in mind when dealing with any cervical lump.

[A comparative study of the prognostic value of morphometric data and of conventional pathological anatomy in laryngeal epidermoid carcinoma]. / Estudio comparativo del valor pronóstico de los datos morfofotométricos y de la anatomía patológica convencional en el carcinoma epidermoide de laringe.

At the moment the use of quantitative techniques is not very frequent in standard anatomopathologic studies of epidermoid carcinoma of the larynx. By "multiple linear regression" the authors show a closed relationship between survival and conventional anatomopathologic data as grade of differentiation and of lymphoid infiltration of the primary tumor.

[The prognostic value of conventional pathological anatomy in laryngeal epidermoid carcinoma]. / Valor pronóstico de la anatomía patológica convencional en el carcinoma epidermoide laríngeo.

The anatomopathologic study of epidermoid carcinoma of the larynx is a reason for many publications in the international scientific community in spite of the apparent histologic similarity of this type of tumor. After a careful review from wide material the authors make reference to the prognostic value of certain anatomopathologic finding.

[A morpho-photometric study of laryngeal epidermoid carcinoma]. / Estudio morfofotométrico del carcinoma epidermoide de laringe.

At the moment the use of quantitative techniques in anatomopathology is more and more frequent. In this study the authors use for the first time the morpho-photometry approach in epidermoid carcinomas of the larynx coming from filed material. In this way they are checking if this method adds anything to conventional anatomopathology.

[Hemifacial malignant granuloma as clinical manifestation of peripheral T-cell lymphoma]. / Granuloma maligno mediofacial como manifestación clínica del linfoma de células T de localización periférica.

The present clinical and pathological study describes the cases of two patients having infiltrate and ulcerous lesions of the nose, hard palate and rhinopharynx clinically consistent with a malignant midline granuloma. Histologically, infiltrates presented atypical lymphoid cells around small vessels and damage of the vascular wall. Immunohistologic study, using monoclonal antibodies on both fresh and paraffin embedded tissues, led to the positive diagnosis of peripheral lymphoma of T cells.

[Prognostic value of the degree of differentiation and the peri-tumor lymphoid infiltration in epidermoid carcinoma of the larynx]. / Valor pronóstico del grado de diferenciación y el infiltrado linfoide peritumoral en el carcinoma epidermoide de laringe.

By multiple linear regression the authors show a closed relationship between survival and conventional anatomopathologic data as grade of differentiation and of lymphoid infiltration of the primary tumor. This retrospective pathological study showed that various degrees of squamous cell differentiation may be recognized for malignant laryngeal lesions and that such distinction may be of prognostic significance.

[Laryngeal fibrolipoma: a case report]. / Fibrolipoma laríngeo. Caso clínico.

A case of laryngeal fibrolipoma, a rare tumor, is presented. The histopathology, symptoms, diagnosis, treatment, and related literature are reviewed.
