Summary
Febrile ulceronecrotic Mucha-Habermann disease, a severe pityriasis lichenoides variant, can present with systemic symptoms and herpes simplex virus infection. T-cell clonality may be a prognostic marker, but more research is needed.
Area of Science:
- Dermatology
- Immunology
- Infectious Diseases
Background:
- Pityriasis lichenoides et varioliformis acuta (PLEVA) encompasses a spectrum of disorders, including the rare and severe Febrile Ulceronecrotic Mucha-Habermann disease (FUMHD).
- The etiology of PLEVA and its variants remains unclear, with ongoing debate regarding whether they represent preneoplastic conditions or reactive responses to infectious or antigenic stimuli.
Observation:
- This report details a case of FUMHD associated with a herpes simplex virus (HSV) infection.
- The patient presented with severe systemic symptoms characteristic of this rare disease variant.
Findings:
- Analysis of the case revealed no significant T-cell clone, suggesting a lack of clonality in this particular presentation.
- Previous reports on T-cell receptor polymerase chain reaction (PCR) results in FUMHD are limited, with only eight cases documented.
Implications:
- The presence or absence of T-cell clonality may serve as a prognostic indicator in FUMHD, although further investigation with more cases is required.
- Increased awareness of FUMHD is crucial due to its potential for rapid and severe progression.
- Understanding the role of infectious agents like HSV in FUMHD pathogenesis is important for potential therapeutic strategies.

01:23Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
01:28Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
01:27Cytomegalovirus 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...
01:20Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
01:17Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
