To determine the histopathological pattern of skin cancer in Madinah region of Kingdom of Saudi Arabia (KSA). Methods: This is a retrospective study including all cases with a histological diagnosis of skin cancer diagnosed at the Department of Pathology, King Fahad Hospital, Madinah, Saudi Arabia, between January 2006 and December 2017. Data included age, gender, site and histology of the tumor were collected from histopathological reports and analyzed using Statistical Package for the Social Sciences (SPSS) Version 21. Results: Among the 202 cancer cases studied in our series, there were 124 (61.4%) cases of basal cell carcinoma (BCC), 33 (16.3%) cases of squamous cell carcinoma (SCC), 14 (6.8%) cases of mycosis fungoides (MF), 12 (5.8%) cases of dermatofibrosarcoma protuberans (DFSP) and 7 (3.7%) cases of malignant melanomas (MM). The male to female ratio for all cases was 2.2:1. The ages ranged from 5 to 100 years with a mean age of 60.1±15 years. The peak age distribution was in the 60-69 year group. The most common site involved in BCC and SCC was the head and neck (92.7% and 66.7%) respectively). Acral distribution of MM was seen in 57.1% of the cases. Conclusion: Our data based on the histopathology history in the Madinah region match that in the world literature and Saudi national studies.

Background: Cutaneous melanoma is one of the most invasive and lethal skin malignant tumors. Compared to primary melanoma, metastatic melanoma (MM) presents poorer treatment outcomes and a higher mortality rate. The tumor microenvironment (TME) plays a critical role in MM progression and immunotherapy resistance.

Generalized pustular psoriasis (GPP) is a rare human autoinflammatory disorder with life-threatening systemic effects. Keratinocyte-derived interleukin (IL)-36 signaling has been identified as a key mediator of immune response in the skin of affected individuals. Recognition of various mutations along the IL-36 axis and the downstream nuclear transcription factor κB (NF-κB) signaling have established GPP as genetically, immunologically, and histopathologically distinct and amenable to immunomodulation, which is epitomized by the recent success of IL-36 antagonism.

Occupational exposure to crystalline silica is etiologically linked to an increased incidence of systemic sclerosis (SSc), also called Erasmus syndrome. The underlying mechanisms of silica-related SSc are still poorly understood. We demonstrated that early and repeated silica exposure contribute to the severity of SSc symptoms in the hypochloric acid (HOCl)-induced SSc mouse model.

Melanoma, recognized as one of the most aggressive forms of skin cancer, continues to show a steady rise in global incidence. While Bacillus Calmette-Guérin (BCG) has been identified as a potential intralesional therapy for melanoma, its therapeutic efficacy remains suboptimal. This study introduces a novel thermosensitive hydrogel formulated with BCG lysates and either OVA peptide or tumor cell lysates (PPP-BCG-OVA/TL).

We report a case of Acanthamoeba infection in an HCT recipient with steroid-refractory GVHD. We highlight the multiple challenges that free-living ameba infections present to the clinician, the clinical laboratory, transplant infectious disease for review, hospital epidemiology if nosocomial transmission is considered, and public health officials, as exposure source identification can be a significant challenge. Transplant physicians should include Acanthamoeba infections in their differential diagnosis of a patient with skin, sinus, lung, and/or brain involvement.
