Context: Pruritic papular eruption (PPE) is a chronic eruption of papular and pruritic lesions of unknown etiology, symmetrically distributed over trunk and extremities. These are common cutaneous manifestations in HIV patients. It is an important cause of HIV-related morbidity. PPE can be the first marker of HIV. Their etiology, histopathological findings, and associated factors vary from region to region. There are no clear data available on the etiology, exact spectrum of the condition, histopathological findings, or treatment of PPE.
Aims: The study is aimed at documenting the etiology, CD4 count, and its histopathological correlation in HIV-infected patients.
Settings And Design: An observational study conducted in Government Medical College, Patiala.
Subjects And Methods: Two-year data regarding history, HIV status, cluster of differentiation 4 (CD4) cell count, and skin biopsy of clinically suspected PPE patients with known HIV status were analyzed.
Statistical Analysis Used: All the results were then statistically analyzed. Categorical data were analyzed by Chi-square test, and one-way Spearman's rho test was used for multiple group comparison.
Results: Data of 50 eligible patients were analyzed. The majority of the patients were female (between 21 and 50 years of age). The most common histopathological patterns were of papular urticaria, scabies, and drug reaction, and the others less common PPE were polymorphic light eruption and eosinophilic folliculitis. Patients with papular urticaria (32%) had significantly lower mean CD4 counts (157 cells/mm), while in scabies, the mean CD4 count (376 cells/mm) was higher.
Conclusions: We conclude that histopathology helps in specifying the pattern of PPE and its etiology. It can be a marker of advanced HIV infection. Thus, correlation between the histopathology, clinical diagnosis, and CD4 counts helps to know the disease process.

Hookworm infection represents a major global disease burden, in terms of both morbidity and economic impact, and there has been a resurgence of hookworms in developed nations where these parasites were once thought to be eradicated. Hookworms can infest humans or other mammals as their primary hosts depending on the species. The 2 most common species that seek human hosts-Necator americanus and Ancylostoma duodenale-enter the body through the epidermis, and hookworm infection may manifest as a pruritic and papular inflammatory reaction know as ground itch.

Article Synopsis
- - A 30-something man with newly diagnosed HIV (CD4 count of 292) showed symptoms like headaches and weakness in limbs, alongside a history of skin rashes that had resolved on their own.
- - Imaging tests (CT and MRI) revealed significant brain swelling and two enhancing masses, indicating severe issues possibly related to both cerebral toxoplasmosis and neurosyphilis.
- - The patient received treatment with trimethoprim/sulfamethoxazole and intravenous penicillin G, leading to a full resolution of his symptoms.

Article Synopsis
- The study focuses on vulvar acantholytic dyskeratoses, which are rare skin conditions affecting the vulva and perineum, with a goal to improve classification and understanding for gynecologic pathologists.
- Between 1990 and 2023, 16 cases of vulvar acantholytic dyskeratoses were analyzed, mostly affecting women aged 36 to 79, with many presenting asymptomatic or pruritic lesions predominantly on the labia majora.
- Histologically, these conditions showed features like acantholysis, with some patients responding to local excision or corticosteroids; however, no clear distinction was found between sporadic and syndromic cases based on
Key Clinical Message: Although rare, crusted scabies can affect immunocompetent individuals with no identifiable risk factors. A high index of suspicion, regardless of an individual's immunological status or absence of traditional risk factors, should be maintained by health professionals to facilitate prompt referral to a dermatologist.
Abstract: Crusted scabies is an uncommon variant of human scabies characterized by extensive crusted and scaly hyperkeratotic papules, and plaques resulting from profound proliferation of mites in the skin.
Article Synopsis
- A 47-year-old woman with several autoimmune and metabolic conditions presented with a painful skin rash characterized by raised, yellow-centered plaques on sun-exposed areas.
- A biopsy revealed specific histopathological features that led to a diagnosis of annular elastolytic giant cell granuloma (AEGCG), a rare inflammatory skin disorder potentially triggered by sunlight exposure.
- The patient showed significant improvement after being treated with ciclosporin, alleviating symptoms like itching and pain, highlighting the challenges in managing AEGCG, which is often resistant to standard treatments.
