Oral Surg Oral Med Oral Pathol Oral Radiol 2024; 137:362-371. [PMID: 38262774 DOI: 10.1016/j.oooo.2023.12.787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 12/08/2023] [Accepted: 12/13/2023] [Indexed: 01/25/2024]
Abstract
OBJECTIVE To evaluate the prevalence of oral manifestations of leprosy. STUDY DESIGN This systematic review with meta-analysis was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and included cross-sectional studies by 2 independent reviewers in 2 phases, who reported bacilloscopic-confirmed oral manifestations of leprosy. Studies were selected based on predetermined eligibility criteria. Searches in 6 main databases were performed, such as PubMed/MEDLINE, Embase, Scopus, Web of Science, LILACS/BVS, and LIVIVO, in addition to the gray literature. The risk of bias was assessed using the JBI Checklist for Analytical Cross-Sectional Studies, and the quantitative synthesis of the data was performed using the Jamovi 2.3 application. RESULTS Ten studies were included, and the meta-analysis was performed with 917 patients with different types of leprosy. The overall prevalence of oral alterations was 6.0% (95% IC, 0.02-0.11; I2 = 97.01%; Q = 75.56), with plaques (27.2%), infiltrations (18.1%), and macules (15.1%) being the most prevalent fundamental lesions, especially in multibacillary patients. CONCLUSIONS Even though there is no oral pathognomonic lesion of leprosy, this infectious disease can manifest in oral tissues in different ways, depending mainly on the leprosy type and stage of treatment.

Abstract
BACKGROUND Limited research exists on laser treatment of giant congenital melanocytic nevus (GCMN). OBJECTIVE We sought to elucidate the efficacy of the Erbium: YAG laser on GCMN and the histologic factors associated with a positive clinical response. METHODS AND MATERIALS Between 2019 and 2022, we enrolled 30 medium-to-giant CMN patients who underwent Er: YAG laser treatment. All patients received biopsies before and after laser treatments. Clinical efficacy outcomes were evaluated by the investigator's global assessment (IGA), 5-point scale of depigmentation, and Vancouver Scar Scale (VSS) scores at least 6 months after treatment. RESULTS Of the 30 cases, 18 (60.0%) showed improvement (IGA score ≥3). Eight (26.7%) patients showed repigmentation. Eight (26.7%) patients developed hypertrophic scars. The average IGA, depigmentation, and VSS scores were 2.93, 3.57, and 3.20. The IGA score was higher (3.24 ± 1.18 vs. 2.22 ± 0.97, p = 0.031) and a lower repigmentation rate (14.3% vs. 55.6%, p = 0.032) was observed in the cases with Grenz zone. The IGA score was higher (3.33 ± 1.24 vs. 2.13 ± 0.89, p = 0.023) and the repigmentation rate was lower (11.1% vs. 50.0%, p = 0.034) also in the cases with the melanocytes nests with aggregation of melanin. Lesions with superficial ablation resulted in less hypertrophic scar formation than those with deep ablation (5.9% vs. 53.8%, p < 0.05). CONCLUSION The Er: YAG laser demonstrated effective clinical results for GCMNs. The grenz zone and the melanocytes nests with aggregation of melanin are promising predictors of laser efficacy.

Abstract
Extranodal NK/T-cell lymphoma (ENKTL) is a subtype of non-Hodgkin lymphoma mainly derived from NK cells and, uncommonly, T-cells. A diagnostic challenge is presented when an atypical phenotype and gene rearrangement are encountered. Herein, we report a case of ENKTL with CD20 expression and IGH gene rearrangement, which is extremely rare. A 57-year-old female patient was seen in 2021 due to a nodule on her left leg and simultaneously impaired eyesight for 6 months. Skin biopsy and immunohistochemistry were performed. The lymphoid cells were positive for CD3, CD56, granzyme B, and TIA-1, partially positive for CD2, and mildly positive for CD20. In situ hybridization for Epstein-Barr virus was positive. Molecular studies revealed immunoglobulin heavy chain (IGH) gene rearrangement, while no T-cell receptor gene rearrangement was detected. The positron emission tomography scan showed that the lymphoma affected bilateral adrenal glands, pelvic cavity, peritoneal cavity, small intestine, skin, and subcutis of the bilateral lower extremities of the patient. Her disease progressed despite eight cycles of chemotherapy and radiation therapy. The importance of this case lies in the atypical phenotype and IGH gene rearrangements, necessitating comprehensive interpretation of clinicopathological data.

Abstract
Cutaneous round cell neoplasms (RCNs) are among the most common skin tumors of dogs. Although a diagnosis can be made in most cases following the examination of H&E-stained routine samples, less-differentiated neoplasms can exhibit overlapping morphologic features that may be challenging to the pathologist, and require immunohistochemistry or molecular testing to reach a final diagnosis. Many patients with cutaneous RCNs are initially seen by a general practitioner and are not referred to a veterinary teaching hospital until a diagnosis has been made. For this reason, anatomic pathology residents at some academic or other training institutions may not be exposed frequently to RCNs during the surgical biopsy service as part of their residency training. In an attempt to fill that gap, here we review the key routine histologic features of canine cutaneous RCNs.

Abstract
BACKGROUND The major intrinsic cause of facial skin degeneration is age, associated with extrinsic factors such as exposure to sun. Its major pathologic causes are degeneration of the elastin matrix, with loss of oxytalan and elaunin fibers in the subepidermal region, and actinic degeneration of elastin fibers that lose their functional properties in the deep dermis. Therapy using autologous adipose mesenchymal stem cells for regeneration of extracellular matrix in patients with solar elastosis was addressed in qualitative and quantitative analyses of the dermal elastic fiber system and the associated cells. METHODS Mesenchymal stem cells were obtained from lipoaspirates, expanded in vitro, and introduced into the facial skin of patients submitted after 3 to 4 months to a face-lift operation. In the retrieved skin, immunocytochemical analyses quantified elastic matrix components; cathepsin K; matrix metalloproteinase 12 (macrophage metalloelastase); and the macrophage M2 markers CD68, CD206, and hemeoxygenase-1. RESULTS A full de novo formation of oxytalan and elaunin fibers was observed in the subepidermal region, with reconstitution of the papillary structure of the dermal-epidermal junction. Elastotic deposits in the deep dermis were substituted by a normal elastin fiber network. The coordinated removal of the pathologic deposits and their substitution by the normal ones was concomitant with activation of cathepsin K and matrix metalloproteinase 12, and with expansion of the M2 macrophage infiltration. CONCLUSION The full regeneration of solar elastosis was obtained by injection of in vitro expanded autologous adipose mesenchymal stem cells, which are appropriate, competent, and sufficient to elicit the full structural regeneration of the sun-aged skin.

Abstract
Background Acquired elastotic hemangioma is a benign vascular proliferation that typically presents as an asymptomatic red plaque on a sun-exposed site of an adult. Material and Methods The PubMed database was used to search the following words: acquired, angioma, arm, basal, carcinoma, cell, elastosis, elastotic, exposed, forearm, hemangioma, solar, sun, and vascular. The relevant papers and reference cited generated by the search were reviewed. The features from a case series of 11 patients with acquired elastotic hemangioma are presented. In addition, a comprehensive review of the characteristics of this unique hemangioma-not only in our 11 patients but also in the previously reported 34 individuals with this lesion-is provided. Results Acquired elastotic hemangioma, reported in 45 patients (24 women and 21 men), typically appeared as an asymptomatic solitary red plaque in sun-exposed areas-most commonly the forearm--of adults aged 50 years or older. The pathology shows a proliferation of vascular channels-surrounded and intertwined by intense solar elastosis--in the upper dermis, located parallel to the overlying epidermis, and separated from it by a zone of normal-appearing superficial papillary dermis. There was extensive solar elastosis surrounding and between the new blood vessels; some of the endothelial cells protrude (in a hob-nail pattern) into the vessel lumen. The clinical differential diagnosis includes basal cell carcinoma and the pathologic differential diagnosis includes other benign, malignant, and reactive vascular lesions. Ultraviolet radiation may contribute to the pathogenesis of this hemangioma since it occurs on sun-exposed sites. There was no recurrence of the lesion following either excision or observation. Conclusions The possibility of acquired elastotic hemangioma should be considered by clinicians when they encounter an older individual with a new red plaque on a sun-exposed site that clinically appears to be a superficial basal cell carcinoma.

Abstract
BACKGROUND Eosinophilic angiocentric fibrosis (EAF) and granuloma faciale (GF) share several histopathologic features, including eosinophil-rich inflammation, microangiitis, and progressive fibrosis. Concurrent presentation of EAF and GF suggests a pathogenetic link between them. OBJECTIVES To identify histologic findings that tell them apart and construe the pathogenetic mechanisms behind each morphologic variable, 14 immunohistochemical markers were used to study the cells subpopulations in 14 cases of GF and 3 cases of EAF. MATERIALS AND METHODS The lesions were classified according to their stage of development. The antibodies studied were: CD4, Foxp3, CD8, granzymes A and B, perforin, granulysin, CD20, CD56, CD68, ICAM-1, CD34, CD105, and 1A4. RESULTS The intensity of the sclerotic response and the density of 1A4-immunostained cells were significantly higher in EAF. In both diseases, CD68 cells were the most numerous, followed by CD20, CD8, and CD4 cells. About 30% of cells expressed ICAM-1. Among cells with cytotoxic granules, granulysin-positive cells were the most frequent. CONCLUSIONS Differences between GF and EAF were found to be mostly like due to anatomic site (usually skin of the face vs. sinonasal cavity) and stage of the disease development (usually earlier in cutaneous lesions because of their visibility). Innate and adaptive immunity, including B cells, T cells, and cytotoxic granules have a role in their pathogenesis.

Abstract
Granuloma faciale is a chronic, benign, cutaneous vasculitis with well-established clinical and morphological patterns, but with an unknown etiology. This study describes clinical and pathologic aspects of patients diagnosed with granuloma faciale. The authors analyzed demographic, clinical, morphological and immunohistochemical data from patients with a final diagnosis of granuloma faciale, confirmed between 1998 and 2012. There was a proportional and mixed inflammatory infiltrate, Grenz zones were present in almost all the samples. Immunophenotyping confirmed a higher intensity of T lymphocytes than B lymphocytes in thirteen samples, with a predominance of T CD8 lymphocytes in 64% of cases, in contrast to the literature, which indicates that the major component is T CD4 lymphocytes. All cases were positive for IgG4 but the majority (12/14) had less than 25% of stained cells. The pathogenesis of granuloma faciale remains poorly understood, making studies of morphological and immunohistochemical characterization important to better understand it.

Abstract
BACKGROUND Sarcoidosis is a multi-system granulomatous disease of unknown etiology. The skin is involved in 25% of cases. Studies on cutaneous sarcoidosis from our region are lacking. OBJECTIVES This study was conducted to describe clinical and histopathologic findings in all patients diagnosed with cutaneous sarcoidosis at the American University of Beirut Medical Center between 1992 and 2010 and to compare findings with those published in the literature. METHODS Clinical charts of patients with cutaneous sarcoidosis were retrospectively reviewed. Extracutaneous lesions were classified by organ involvement. Treatment was documented. Pathology specimens were reviewed. RESULTS Cutaneous sarcoidosis was diagnosed in 76 Lebanese patients, 79% of whom were women. Mean age at diagnosis was 48 years. A total of 29% of patients had systemic disease that was commonly associated with lupus pernio lesions and subcutaneous sarcoidosis. The most common cutaneous lesions were sarcoidal plaques. The histopathologic features in our series did not differ from those described in the literature, except for the documented presence of a grenz zone. Interestingly, 23% of biopsy specimens contained perineural granulomas, raising the possibility of tuberculoid or borderline tuberculoid leprosy. Foreign bodies were detected in 10% of cases (all had systemic involvement), supporting the opinion that sarcoidosis and granulomatous foreign body reaction are not mutually exclusive. CONCLUSIONS The clinical and histopathologic features of cutaneous sarcoidosis patients in the present series are generally comparable with those published in the literature, with minor differences. Clinically, the most commonly seen lesion was plaque. Microscopically, cutaneous sarcoidosis may exhibit a grenz zone and may show perineural inflammation and foreign bodies.
