Menalocytic nevi are benign localized pigmented lesions, which usually occur on the cutaneous surface of the body but rarely on the mucous membranes. It is comparatively easy to encounter pigmented lesions of the oral cavity, but the melanocytic nevi of the pharyngeal wall are extremely rare worldwide and, to the best of our knowledge, there is no reported case of melanocytic nevus arising from pharyngeal wall. We report a case of a pigmented lesion on the posterior wall of pharynx, which was microscopically confirmed as oropharyngeal blue nevus.

Background: Oral melanoacanthoma is not common. It occurs mostly on the buccal mucosa. Since it happens suddenly and progresses rapidly, it clinically resembles melanoma. Melanoacanthoma occurs in regions susceptible to trauma. The clinical presentation of the lesion is not enough to diagnose it; therefore, tissue biopsy is necessary to exclude malignancy. Case report: We report a case of oral melanoacanthoma in a rare mucosal location in a 21-year old female patient in whom generalized gingival melanoacanthoma was related to the use of the teeth whitening strips. This irritating factor increased melanocyte activity in the gingival tissues and labial mucosa. Discussion: Oral melanoacanthoma is a rarely encountered pigmented lesion in the oral cavity and is especially uncommon in the gingiva. It is a reactive lesion affecting the mucous membranes with no risk of malignant transformation. This case report shows that teeth whitening strips may trigger oral melanoacanthoma in susceptible individuals. Long-term irritation of the oral tissues may increase the number of dendritic melanocytes throughout the epithelium and accordingly increase the brown pigmentation of the oral cavity.  Eliminating all possible local sources of irritation and ruling out other causative factors are the standard first step in the treatment of oral melanoacanthoma. Conclusions: This case shows the importance of including oral melanoacanthoma in the differential diagnosis of diffuse gingival pigmented lesions.

ABSTRACT Aim The aim of this study is to report a clinical case of oral nevus. Background Nevus is a congenital or acquired benign neoplasia that can be observed in the skin or mucous membranes. It is an uncommon condition in the oral mucosa. When it does occur, the preferred location is on the palate, followed by the cheek mucosa, lip and tongue. Case report In this case study, we relate the diagnosis and treatment of a 23-year-old female patient with an irregular, pigmented lesion of the oral mucosa that underwent excisional biopsy resulting in a diagnosis of intramucosal nevus. Conclusion Nevus can appear in the oral mucosa and should be removed. Clinical significance It is important for dental professionals to adequately categorize and treat pigmented lesions in the mouth.

Agminated nevus is a cluster group of melanocytic nevi confined to a localized area of the body. There are many pigmented lesions described in the literature as agminated, such as blue nevi, multiple lentigines and Spitz nevi, but only a few cases of congenital agminated melanocytic nevi have been described. We report a case of a male child who presented with congenital agminated nevi, emphasizing the importance of physical examination, dermoscopy, histopathological evaluation, differential diagnosis and follow up to rule out the possibility of dysplastic or malignant changes.

Congenital Melanocytic Nevi

We present a 6-month-old male patient, who was consulted with dermatologist by his parents, because of a pigmented lesion, present since birth, covering almost the all skin of the back and buttocks.  A sharply bordered, unequally coloured congenital pigmented nevus, measuring approximately 21 cm in diameter was observed in the whole body skin examination. The lesion was affecting the lower 2/3 of the skin of the back and the top half of the gluteus area, extending to the lateral part of the tors, forward the abdomen and the upper lateral part of the hips, composed by multiple darker-pigmented nests and several lighter areas, with single depigmented zones, hairy surface, irregularly infiltrated on palpation. Congenital melanocytic nevi are presented in approximately 1% of newborns, while giant congenital melanocytic nevi (GCMN) are the most uncommon subtype of them; with occurrence rate 1 in 50,000 births. They affect 2% of a total body surface or presenting in a diameter larger than 20 cm in older children. Although not common, the possible malignant transformation remains one of the most important considerations related to them, as the related lifetime risk of melanoma is 4% to 10%. Treatment recommendations include non-surgical methods as dermabrasion only within the first two weeks of life, for prevention the possible melanocytic deeper migration, while serial surgical excisions or tissue expanders could be useful treatment tool even in later stages. Nevertheless, cosmetic result is not always satisfactory, and the risk of malignant changes remains, in cases of previous melanocytic migration in deeper layer. Recent article suggests the potential role in the treatment of GCMN with NRAS inhibitor trametinib, approved for treatment of advanced melanoma, associated with underlying NRAS mutations. Although promising, the drug could be useful in paediatric patients, only with associated NRAS gene mutation. It is still unclear whether it could be helpful, independent of the NRAS status.

AbstractCombined nevi (CN), a rare nevus type represent a category of so-called compound tumors. Determined by the presence of two or more different nevus in one biopsy specimen, CN commonly show variable clinical and dermatoscopic features. Therefore, CN could be a diagnostic challenge. We present a 7-year-old Caucasian girl with a pigmented lesion on the arm of no specified duration. Clinical examination showed sharply demarcated pigmented papule. Dermatoscopy revealed a nonchaotic lesion with structureless well defined, minimally eccentric blue area, structureless brown area and brown clods in a symmetric fashion, no vessels and no other clues for melanoma. Histopathology showed a compound common melanocytic nevus, blue nevus in the centre of the lesion with no signs of atypia. Up to now, only 25 cases of CN with dermatoscopic description have been published, withno precise dermatoscopic features established yet. Therefore, studies with larger number of cases are needed for the final conclusions.

According to the authors, the prevalence of SOPR diseases is from 3 to 20%.In a study of 1573 residents of southern China in two age groups who use tobacco and alcohol, the incidence of SOPR was higher among men living in rural areas compared to urban residents. Among women aged 35-44 years, the incidence was higher in urban women, and in the 65-77-year-old group in rural women. In the course of studies in Brazil, among 335 patients older than 60 years, 646 diseases of the SOPR were identified. Similar results were obtained in the analysis of SOPR diseases in the Volgograd region of the Russian Federation

«Man is what he eats,» these words belong to the great Pythagoras. He meant by these words the connection of the origin of consumed food with the spiritual development of man. In fact, a lot depends on the nature of nutrition, the quality of food and, of course, on the degree of its perception by the body. Digestion process begins not in the stomach, but directly in the oral cavity as a result of mechanical processing of products with teeth and under the influence of the secretion of the salivary glands. That is why healthy teeth are the key to the normal functioning of the whole organism — people should start taking care of their teeth from the early childhood and dentists, who are far from being beloved by everybody and are often carelessly evaded, are called upon to help keep the teeth healthy.

In Pregnancy

Background: It is known that hormonal imbalances during pregnancy make women more susceptible to dental problems. High levels of progesterone and estrogen during pregnancy, lead to an increased inflammatory response to dental plaque thus causing predisposing to gum diseases such as gingivitis. If untreated, gingivitis leads to chronic periodontitis which may manifest systemically in form of cardiovascular, endocrine or even respiratory disorders. Also, hyperacidity in the oral cavity due to gastric reflux and vomiting leads to decreased pH thus damaging the tooth enamel making the oral cavity more prone to tooth decay and tooth loss. Studies also show that periodontal disease can also lead to adverse pregnancy outcomes such as pre-term and low birth weight babies. Objectives: We sought to understand the role of oral health in pregnancy. Methods: We identified major articles of interest in the field of oral health in pregnancy and drafted a mini-symposium based on relevant information. Conclusion: Regular dental visits and cognizant efforts to sustain a healthy oral environment can help women in the prevention and treatment of dental issues during pregnancy. The paper highlights the common oral manifestations during pregnancy and their local and systemic impact on the body during pregnancy. Furthermore, it also emphasizes the importance of good oral health practices to counteract the oral complications and the significance of oral health awareness in pregnant women.
