Summary
A rare case of Kaposi
Area of Science:
- Dermatology and Oncology
- Infectious Diseases
Background:
- Kaposi sarcoma (KS) is an AIDS-defining illness, but can occur in non-HIV individuals.
- Cutaneous KS presents as lesions on the skin, often affecting the lower extremities.
Observation:
- A 65-year-old diabetic man presented with painful, reddish-purple patches and plaques on palms and soles.
- Skin biopsy revealed epidermal acanthosis and spongiosis, with dermal vascular proliferation and inflammatory infiltrate.
- Immunohistochemistry was positive for CD34 and CD68; PCR confirmed human herpesvirus 8 (HHV-8) positivity.
Findings:
- The patient was diagnosed with cutaneous Kaposi sarcoma.
- The HHV-8 association was confirmed via PCR, indicating a viral etiology.
- The presentation on palms and soles is atypical for classic KS.
Implications:
- This case highlights that KS can occur in immunocompetent individuals, albeit rarely.
- It underscores the importance of considering KS in the differential diagnosis of unexplained skin lesions, even in non-HIV patients.
- Early diagnosis and treatment are crucial for managing KS and preventing complications.

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
