Synchronous laryngeal cancer.

Multiple primary cancers are usually defined as primary malignant tumors of different histological origins in one person. Synchronous cancers are defined as two or more primary cancers diagnosed in the same patient at the same time or within six months after identifying the first tumor, and those cancers that develop at more than a six-month interval are termed as metachronous multiple primary cancers. Our study comprised of a patient with synchronous laryngeal cancer with double localizations. The case was solved through surgical excision of the tumors. Histopathological and immunohistochemistry examinations revealed synchronous laryngeal cancer. Laryngeal cancer should usually be managed through surgical resection, followed by oncological treatment.

Influence of tumor topography on clinical-morphological profile of laryngeal malignancies.

AIM: Laryngeal cancers are redoubtable because they are still diagnosed in advanced stages which results in poor survival and the decline of life quality. The authors intend to identify if the tumor topography influences clinical behavior, the morphological profile and therapeutic strategy. PATIENTS, MATERIALS AND METHODS: The study group included 188 patients with laryngeal malignancies diagnosed and treated in an Ear, Nose and Throat (ENT) Department. The patients have been divided into four groups according to the tumor topography and extension. Three categories of parameters were defined (epidemiological, clinical, and morphological) and analyzed comparatively between the four groups using filter scales and the χ² (chi-squared) correlation test. RESULTS: Epidemiological parameters (sex, age, socio-economic status) showed no significant differences between the four groups. Clinical parameters (symptoms, lymphadenopathies, surgical procedures, and hospitalization) instead registered significant differences between the four groups. Morphological parameters (longitudinal diameter, transverse diameter, shape, gross aspect, histopathological aspect, grade, local invasion - pT, lymph node invasion - pN, metastases - pM and tumor stage), excepting shape, registered too significant differences between the four groups. The analysis of the whole set of parameters in each group revealed different, distinct profiles for each of the topographic groups, especially for glottic and large tumors. Our results concerning the entire series of tumors ranged in the limits of variation of each of the parameters observed in the literature. CONCLUSIONS: Our study revealed that tumors placed in different regions of the larynx have distinct profiles from epidemiological, clinical, and morphological points of view. However, the profile of our entire group of tumors proved to be comparable with the literature data.

Chondrosarcoma of the hyoid bone: a case report.

Chondrosarcoma is a malignancy of the mesenchymal tissue derived from transformed cells that produce the cartilage matrix. In the neck area, it represents less than 0.5% of malignant tumor pathology. Chondrosarcoma of the hyoid bone is extremely rare, only 20 cases having been published so far (PubMed 2014). We present the case of a 30-year-old patient from the urban area, admitted in the ENT (Ear, Nose & Throat) Emergency Service with inspiratory dyspnea, dysphagia, stomatolalia, with evolutive and progressive clinical history of 2-3 months. Endoscopic examination revealed a pharyngolaryngeal tumor process located in the right vallecula, who by mass effect displaces the above-hyoid epiglottis. CT (computerized tomography) scan described a cervical polycystic tumor aspect, with multiple septae and inside calcifications with a diameter of 3-4 mm. Surgery consisted in removal of the tumor process together with the hyoid bone. Histopathological and especially immunohistochemical examination established the diagnosis of low-grade chondrosarcoma of the hyoid bone. For assessment of the phenotype of the tumor cells, the following immunohistochemical markers were used: p53, Ki67. The patient followed radiochemotherapic oncological treatment and returned for regular follow-ups. There was a positive development with no signs of regional or remote relapse or metastasis for 24 months after surgical treatment. Surgery is the treatment of choice, with complete removal of the tumor, with chemoradiation playing an adjuvant role. Regular tracking of the patient is mandatory.
