Summary
This case study describes idiopathic figurate erythema, a rare skin condition, in a 39-year-old woman. The condition presented as annular plaques with a unique histologic finding of neutrophil-dominant inflammation.
Area of Science:
- Dermatology
- Histopathology
Background:
- Idiopathic figurate erythema is a rare inflammatory dermatosis characterized by annular or polycyclic lesions.
- The exact etiology remains unknown, but it is hypothesized to involve immune system dysregulation.
Observation:
- A 39-year-old woman presented with annular plaques exhibiting central clearing on her back, extremities, and breasts.
- Lesions featured raised, firm, erythematous borders with a trailing scale.
- Histologic examination revealed a superficial dermal perivascular inflammatory infiltrate.
Findings:
- The infiltrate was predominantly composed of neutrophils, with a smaller number of mononuclear inflammatory cells.
- The clinical and histological findings support a diagnosis of idiopathic figurate erythema.
Implications:
- This case highlights the importance of considering idiopathic figurate erythema in the differential diagnosis of annular skin lesions.
- The prominent neutrophilic infiltration observed in this case may offer insights into the pathogenesis of this condition.
- Further research is warranted to elucidate the specific mechanisms driving neutrophilic involvement in idiopathic figurate erythema.

01:25Endocarditis 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...
01:26Acute Inflammation II: Cellular Phase
The cellular phase of acute inflammation is a tightly orchestrated sequence of events that recruits leukocytes, primarily neutrophils, to sites of tissue injury or infection. Following the initial vascular changes, this phase ensures effective immune cell migration, activation, and function at the affected site to eliminate pathogens and initiate tissue repair.Leukocyte Recruitment CascadeLeukocyte recruitment happens in four steps: margination, adhesion, transmigration, and chemotaxis. Reduced...
01:30Classification of Leukocytes
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...
