KOH test on a vaginal wet mount, showing slings of pseudohyphae of Candida albicans surrounded by round vaginal epithelial cells, conferring a diagnosis of candidal vulvovaginitis. The KOH test , also known as a potassium hydroxide preparation or KOH prep , is a quick, inexpensive fungal test to differentiate dermatophytes and Candida albicans ...
PECAM-1 is expressed by many solid tumor cell lines such as hemangioma, angiosarcoma, Kaposi’s sarcoma, breast carcinoma, glioblastoma, colon carcinoma, skin carcinoma and other tumor cell lines. [27] On the surface of these tumor cells PECAM-1 mediates the adhesion to endothelial cells. [28]
It can be used to diagnose α1-antitrypsin deficiency if periportal liver hepatocytes stain positive. Aggregates of PAS-positive lymphocytes are present in epidermis in Mycosis fungoides and Sézary syndrome, called Pautrier microabscesses. Ewing sarcoma; Erythroleukemia, a leukemia of immature red blood cells. These cells stain a bright fuchsia.
neglected squamous cell carcinoma skin of scalp Advanced squamous cell carcinoma, excision specimen. Note invasion subcutaneous tissue. Cutaneous squamous-cell carcinoma (cSCC), also known as squamous-cell carcinoma of the skin or squamous-cell skin cancer, is one of the three principal types of skin cancer, alongside basal-cell carcinoma and melanoma.
Malassezia furfur is a fungus that lives on the superficial layers of the dermis.It generally exists as a commensal organism forming a natural part of the human skin microbiota, but it can gain pathogenic capabilities when morphing from a yeast to a hyphal form during its life cycle, through unknown molecular changes.

Kaposi's sarcoma-associated herpesvirus (KSHV), also called HHV-8, is present in almost 100% of Kaposi sarcoma lesions, whether HIV-related, classic, endemic, or iatrogenic. [22] KSHV encodes oncogenes , microRNAs and circular RNAs that promote cancer cell proliferation and escape from the immune system.
Basal-cell carcinoma (BCC), also known as basal-cell cancer, basalioma [7] or rodent ulcer, [8] is the most common type of skin cancer. [2] It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it . [ 1 ]
Phaeohyphomycosis is a diverse group of fungal infections, [6] caused by dematiaceous fungi whose morphologic characteristics in tissue include hyphae, yeast-like cells, or a combination of these. [7] It can be associated with an array of melanistic filamentous fungi including Alternaria species, [8] Exophiala jeanselmei, [9] and Rhinocladiella ...
