Summary
Large plaque parapsoriasis (LPP) is a rare scaly skin condition. This report details an unusual ichthyosiform presentation of LPP, highlighting its rarity in dermatological literature.
Area of Science:
- Dermatology
- Pathology
Background:
- Large plaque parapsoriasis (LPP) is an idiopathic, chronic scaly dermatosis.
- LPP is commonly seen in middle-aged individuals across all races and regions.
- LPP and its variants are closely associated with the patch stage of mycosis fungoides.
Purpose of the Study:
- To report a rare case of ichthyosiform large plaque parapsoriasis.
- To highlight the diagnostic challenges and clinical significance of rare LPP variants.
Main Methods:
- Case report and literature review.
- Clinical and histopathological examination of the patient's skin lesions.
Main Results:
- The patient presented with an ichthyosiform variant of LPP, a presentation not commonly described.
- Histopathological findings were consistent with LPP, despite the unusual ichthyosiform morphology.
Conclusions:
- Ichthyosiform LPP is a rare variant of parapsoriasis that requires careful clinical and pathological evaluation.
- Recognition of rare LPP presentations is crucial for accurate diagnosis and management, distinguishing it from mycosis fungoides.

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...
01:27Diversity of Protists II
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
01:23Cirrhosis I: Introduction
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
