Diagnosis is based on clinical and histopathological findings, and most lesions are asymptomatic and regress spontaneously with time Abstract Background: Multifocal epithelial hyperplasia is a pathology of the oral mucosa which has been reported in diverse ethnic groups. Human papillomavirus (HPV) types 13 and 32 DNA has been detected in these lesions Multifocal papilloma virus epithelial hyperplasia is an infection of the oral mucosa produced by human papilloma virus types 13 and 32, which primarily bilaterally affects lips, lateral borders of tongue, and buccal mucosa.

Multifocal epithelial hyperplasia is a virus related disease affecting the oral mucosa in children and there are reports of this disease in several ethnic groups of the world. The aim of this study is to present th Human papilloma virus (HPV) infections of the oral mucosa presents with various clinical and histopathologic features in relation with the causative HPV type and chronicity and the extent of the infection. 1 The entity is known by several names based on histopathologic variations such as focal epithelial hyperplasia, oral florid papillomatosis, verrucous hyperplasia, oral florid verrucosis. Multifocal epithelial hyperplasia (MFEH), also referred to as Heck disease, is a virus-induced benign proliferation of the oral squamous epithelium that arises primarily in children and adolescents.

  2. Multifocal epithelial hyperplasia (MEH) appears more commonly in children, but there are some communications in adults. It is characterized by the presence of multiple slow growing, papulo-nodular, elevated, and smooth surfaced asymptomatic lesions. Usually, they are sessile, round, or oval, well defined nodules with color similar to the normal.
  3. 1. Introduction. Multifocal epithelial hyperplasia (MEH) is an uncommon disease characterized by the proliferation on the oral mucosa of multiple papulonodular lesions, which are smooth, soft on palpation and generally asymptomatic (1-5).It has mainly been observed among isolated groups of native Indians in North, Central and South America and in other very small population groups in Europe.
  4. Multifocal epithelial hyperplasia, also known as Heck's disease, is not a common pathology, which is well-known to most physicians. Therefore, asymptomatic proliferation of the oral mucosa has been reported in the literature with differences in various geographic regions. Here, we report unique cases of multifocal epithelial hyperplasia
  5. Multifocal epithelial hyperplasia (MEH) is a benign, rare, familial disorder, characterized by soft, circumscribed, multiple, sessile nodular elevations of the oral mucosa, primarily associated with human papillomavirus (HPV) types 13, 32. Geographically, it is more prevalent in North, South, and Central American-Indians (Waimiri-Atroari Indians) and less common in caucasians

It is one of the common manifestations of human papilloma virus (HPV) infection of the lower anogenital tract. It is caused by HPV types 6 and 11.

Neuroendocrine cell hyperplasia and tumorlets may coexist with carcinoid tumors. In the absence of lung injury (leading to reactive pulmonary neuroendocrine cell hyperplasia), DIPNECH is considered a preinvasive condition that may develop into carcinoid tumors, and imaging follow-up is required. DIPNECH typically manifests in the fifth to sixth. Focal epithelial hyperplasia is a benign epithelial proliferation that often undergoes spontaneous regression. Removal of individual lesions by surgical excision or laser ablation for cosmetic purposes is feasible when a few lesions are present, but impractical when lesions are more numerous and widespread.

Pathology. It represents a clinicopathologic spectrum ranging from focal, incidental microscopic findings to clinically and mammographically evident breast masses. The development of PASH is presumed to be related to the interaction of progesterone in estrogen-activated tissue, and involved tissue contains estrogen and progesterone receptors Spawning Rash - Gross Pathology. The bacterium Renibacterium salmoninarum is a small (~ 1.0 μm), intracellular, non-motile diplobacillus, gram +, that is slow growing and a fastidious pathogen.

Nodular prostatic hyperplasia (also termed benign prostatic hyperplasia, or BPH) is a common condition as men age. Perhaps a fourth of men have some degree of hyperplasia by the fifth decade of life. By the eighth decade, over 90% of males will have prostatic hyperplasia Vulvar intraepithelial neoplasia (VIN) refers to particular changes that can occur in the skin that covers the vulva.VIN is an intraepithelial neoplasia, and can disappear without treatment.VINs are benign but if the changes become more severe, there is a chance of cancer developing after many years, and so it is referred to as a precancerous condition

Although SH was originally considered to be a variant of a hemangioma and was suggested to be of mesenchymal, mesothelial, endothelial, and neuroendocrine origin, there is now consensus that SH is derived from primitive respiratory epithelium Autoimmune gastritis is a chronic gastritis where CD4 + T cells target parietal cells; this leads to both parietal cell and chief cell loss with eventual atrophy of the mucosa. The loss of parietal cells creates a state of constant achlorhydria, prompting antral G cells to continuously produce gastrin. 1 Without parietal cells for the feedback loop, the result is a state of hypergastrinemia

All other markers including, epithelial markers (AE1/AE3), smooth muscle markers, and endometrial stromal cell marker (CD10) were non-reactive. HMB45, a marker for PEComa, was also negative.

Atypical ductal hyperplasia (ADH) is a common diagnosis in the mammographic era and a significant clinical problem with wide variation in diagnosis and treatment. After a diagnosis of ADH on biopsy a proportion are upgraded to carcinoma upon excision; however, the remainder of patients are overtreated. While ADH is considered a non-obligate precursor of invasive carcinoma, the molecular. Foveolar hyperplasia is defined as proliferation, elongation, and tortuosity of gastric pits that result in a corkscrew configuration. It is a compensatory tissue response to increased exfoliation of the surface epithelium and represents a visual surrogate for increased cell proliferation and turnover . Although markedly hyperplastic foveolae. Histology of basal cell carcinoma. The key feature of basal cell carcinoma at low power magnification is of a basaloid epithelial tumour arising from the epidermis (figure 1). The basaloid epithelium typically forms a palisade with a cleft forming from the adjacent tumour stroma (figure 2). Centrally the nuclei become crowded with scattered. Hyperplasia of subsurface epithelial structures is a circular noninvasive proliferation of epithelium that forms cysts, papillae and tubular forms. Mitoses are rare and there is minimal basement membrane material or secretion visible. Adenoma has a single layer of epithelium lining tubules, papillae or the cysts
