RARE LARYNGEAL HAMARTOMA: A CASE REPORT.

Hamartoma (from the Greek language, where means defect or an error and denoting a tumor or neoplasm) is a benign tumor-like mass composed of mature tissue or cells that are present in abnormal proportions or show a disorganized arrangement. Hamartomas are rarely seen in the head and neck area and especially rare in the larynx. Only few cases of laryngeal hamartoma have been reported in the literature so far.

Inter-laboratory comparison of Ki-67 proliferating index detected by visual assessment and automated digital image analysis.

Background: Proliferation rate is a major determinant of the biologic behavior of the tumor and provides information that can be used to guide treatment decisions.

Methods: This ring study included 27 pathologists from 14 Institutions, in order to assess inter-observer concordance between pathologists in Croatia. We analyzed Ki-67 proliferative index on ten randomly selected breast cancer samples comparing consistency between visual assessment using light microscopy compared to digital image analyses results from one central laboratory as a referral value.

Colorectal Adenocarcinoma Metastasizing to the Oral Mucosa of the Upper Jaw.

Introduction: Metastases to the oral cavity are uncommon, accounting for only 1% of all oral malignant tumors. When they occur they mostly originate from primary tumors of the lungs, kidney, breast and prostate. Oral metastases from the primary colorectal carcinoma are much more infrequent.

Vascular endothelial growth factor in a recipient cornea acts as a prognostic factor for corneal graft reaction development.

Purpose: To evaluate whether the vascular endothelial growth factor A (VEGF-A) in the recipient cornea measured at the time of penetrating keratoplasty (PK) can act as a prognostic factor for corneal graft reaction development.

Methods: The study included 25 eyes (of 25 patients) scheduled for PK. According to preoperative clinical finding, patients were divided into three groups: inflammatory with neovascularization (n = 11); inflammatory without neovascularization (n = 7); and non-inflammatory (n = 7).

Extranodal lymphomas of head and neck with emphasis on NK/T-cell lymphoma, nasal type.

Purpose: To determine the occurrence, clinical course and outcome of our patients with natural killer/T-cell lymphoma (NKTCL), nasal type. The nasal type of natural killer/T-cell lymphoma (NKTCL), is rare in the European population but is more frequent in Asia, Central and South America where it accounts for 15-20% of all non-Hodgkin lymphomas (NHL). This type of lymphoma is characterized by tissue necrosis and destruction of the nasal cavity and upper aero-digestive tract.

Harmonic scalpel surgical treatment of the tongue angioleomyoma--case report and review of the literature.

Angioleiomyoma is benign soft tissue tumor composed of smooth muscle cells and vascular endothelium, characterized with slow growth, unspecific symptoms and rare malignant transformation. It is very rare in the head and neck region and complete surgical excision is the gold standard for diagnosis and treatment. We present a very rare case of angoleomyoma of the tounge base treated with partial glosectomy with harmonic scalpel which shortened surgical procedure, reduced bleeding and postoperative complications.

Supernumerary breast in an adolescent boy.

We present an adolescent boy with unilateral supernumerary breast. It was a V type by Leung Clasification. Despite the average occurence between 0.

Gastric adenocarcinoma metastases to the alveolar mucosa of the mandible: a case report and review of the literature.

Malignant tumours rarely metastasize to the oral cavity. When they do, such metastases may arise from various locations including the lung, breast, kidney, prostate and colon. Soft tissue oral metastasis from gastric adenocarcinoma is extremely rare, and limited information exists regarding the presentation and work-up of metastatic gastric carcinoma into the oral soft tissue.
