Abstract
Kaposi's sarcoma (KS) represents a type of cancer that usually arises on the skin and very rarely in other organs. KS-associated herpesvirus (KSHV), also known as human herpesvirus-8 (HHV-8) commonly arises in patients with acquired immunodeficiency syndrome (AIDS). Laryngeal involvement of KS is very rare. Our study comprised of three cases with laryngeal KS. All cases were solved through surgical excision of the tumor. Histopathological and immunohistochemistry examinations revealed laryngeal KS. Laryngeal KS should be managed through surgical resection, followed by oncological treatment.

Abstract
Malignant melanoma rarely develops in mucous membranes. Statistical data show that approximately 0.6-9.3% of patients with cutaneous malignant melanoma will develop metastases in the upper aerodigestive tract mucosa, and within these metastatic sites, the least common are the laryngeal and tracheobronchial ones. This exceedingly rare clinical entity has no clear treatment recommendations; radical surgery does not seem to benefit the patient in term of life expectancy. We present the case of a 56-year-old male patient diagnosed with laryngeal and tracheobronchial melanoma metastases. Prior to admission to our clinic the patient had a personal history of malignant melanoma of the nuchal region operated on 7 years ago, malignant melanoma of the gallbladder and metastatic left axillary polyadenopathy for which he underwent surgical treatment 3 months prior. Histopathological and immunohistochemical reports established the diagnosis of laryngeal metastasis of malignant melanoma. Genetic molecular analysis was positive for B-Raf (BRAF) gene and hence Vemurafenib was administered, with a favorable outcome at the one-year follow-up. Nevertheless, there are currently no clear universally accepted guidelines for the treatment of laryngeal melanoma, mainly due to the rarity of this clinical entity. We conducted a review of similar cases reported in the literature. Interestingly, reviewing the cases reported in the literature, it appears that laryngeal metastases of a primary cutaneous melanoma are more common in men, with an average time to metastasis of 4.3 years.

Abstract
Inflammation plays an important role in the pathogenesis of nasal polyps. Understanding the biomolecular action mechanisms of inflammatory elements can contribute to improving the prognosis of these lesions. The study analyzed the distribution and immunohistochemically quantified eosinophils [eosinophil major basic protein (BMK-13)], lymphocytes [cluster of differentiation (CD) 4, CD8, CD20] and plasmocytes (CD138) in both the epithelial and stromal compartment in relation to composite scores, which included specific histopathological parameters for 50 sinonasal polyps. Inflammatory elements predominated at stromal level, the high histological composite scores being frequently associated with increased expression of inflammatory elements. Also, the numerical distribution of inflammatory elements indicated positive linear relations within the groups BMK-13/CD8 and CD4/CD20/CD138, and a negative linear relation between the two groups. This aspect can support the existence of alternative or sequential pathogenic mechanisms involved in the pathogenesis of sinonasal polyps, and the results obtained can be used for a better stratification of patients in order to optimize the therapy.

Abstract
The pleomorphic adenoma is the most frequently encountered tumor of the salivary glands, representing between 45% and 75% of the total number of the tumors of the salivary glands. According to the literature, there are many studies on the immunohistochemical aspects of the myoepithelial cells, present in the pleomorphic adenoma of the salivary gland. A big diversity of mono and polyclonal antibodies, such as the cytokeratins, muscular proteins and other markers, has been used. In our study, we investigated the immunohistochemical aspect of bone morphogenetic protein 6 (BMP6) marker concerning 15 cases of pleomorphic adenomas of the salivary glands. In the immunohistochemical study, we used the paraffin blocks that served for obtaining the sections necessary for the classical histopathological processing by means of the usual stainings. The immunohistochemical study used the enzymatic detection and the LSAB 2 (Labeled Streptavidin-Biotin 2) System technique as the working method. In order to underline the process of epithelial-mesenchymal transition, we also used double sequential immunohistochemical reactions. By the use of the BMP6 marker, we intended to evaluate the reactivity of the various tumor components in the pleomorphic adenomas of the salivary gland, for this marker, taking into consideration its possible involvement in the process of the epithelial-mesenchymal transition. The maximum reactivity for BMP6 was recorded at the level of the normal, excretory, intratubular units, in the luminal cells of the proliferative ductal units, in the myxoid matrix, the cytoplasm of the myxoid stellate cells and the plasmacytoid matrix and the cytoplasm of the chondroid lacunar cells. Some of the cells belonging to the solid, proliferative areas, some of the abluminal cells, that are part of the proliferative ductal units and certain myxoid stellate or plasmocytoid cells contain the S100 protein, which would indicate the existence of some processes of mesenchymal epithelial÷myoepithelial transdifferentiation in the development of this type of salivary tumor. The BMP6 expression is specific to the serous acini salivary cells, which are the most specialized epithelial salivary gland cells. The study demonstrated that the mesenchymal epithelial÷myoepithelial potential of transdifferentiation of the luminal cells that make up the proliferative units is certified by the immunohistochemical expression of some BMP6 purely mesenchymal protein cells.

Abstract
The pleomorphic adenoma, also known as mixed tumor, presents an epithelial and mesenchymal histological structure, being also called epithelioma with altered stroma. The pleomorphic adenoma has a frequency of 70% of major salivary gland tumors, being located preponderantly at the level of parotid gland (52-84%), at the level of submandibular glands (7-17%) and at the level of the other salivary minor salivary glands (3-8%). The purpose of our study was the histopathological analysis of 45 cases of pleomorphic adenoma. The tumors were characterized by an increased structural pleomorphism, given by the multitude of cytological differences and proliferation patterns, and on the other side by the diversity of stromal component.
