Insights

Cytomegalovirus (CMV) was unexpectedly found in skin biopsies of immunocompromised patients with eruptions. Occult CMV in skin may be more common and not the sole cause of these infections.

Area of Science:

  • Dermatology
  • Virology
  • Immunology

Background:

  • Acquired immunosuppression presents diagnostic challenges for cutaneous eruptions.
  • Skin biopsies are crucial for identifying causes of skin conditions in immunocompromised individuals.

Observation:

  • Three immunocompromised patients with diverse skin eruptions underwent biopsy.
  • Unexpected amphophilic, granular, intranuclear inclusions were observed in endothelial cells.
  • These inclusions were consistent with cytomegalovirus (CMV).

Findings:

  • Cytomegalovirus (CMV) was identified in skin biopsy specimens from immunocompromised patients.
  • Occult cutaneous CMV infection may be more prevalent than previously thought.
  • CMV may not be the sole pathogen responsible for the observed skin eruptions.

Implications:

  • Highlights the potential for asymptomatic or occult cytomegalovirus (CMV) in the skin of immunocompromised hosts.
  • Underscores the importance of considering CMV in the differential diagnosis of cutaneous eruptions in immunosuppressed individuals.
  • Emphasizes the need for vigilance regarding polymicrobial infections in immunocompromised patients.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

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...

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,...
