Article Synopsis
  • Most dermatology publications focus on lightly pigmented skin, leaving a knowledge gap regarding black skin and its unique dermatological needs.
  • The article reviews intrinsic characteristics, epidemiological data, and clinical aspects related to various skin conditions prevalent in black individuals, highlighting significant differences with lightly pigmented skin.
  • It also identifies specific dermatoses that are either more common in black skin or unique to it, such as pseudofolliculitis barbae and keloids, and discusses skin cancers and their characteristics in this population.

Article Synopsis
  • * A case involving a 15-year-old male showed symptoms for 3 years, but he achieved complete recovery in just 2 weeks with oral minocycline treatment.
  • * CARP often resembles other skin conditions like pityriasis versicolor and acanthosis nigricans, leading to misdiagnoses, so thorough assessments are essential for proper identification and management.

Article Synopsis
  • Confluent and reticulated papillomatosis (CARP) is a rare skin condition that causes asymptomatic, coalescing papules mainly in young black individuals.
  • Minocycline is typically the preferred treatment but has several potential side effects, including serious allergic reactions and skin discoloration; doxycycline is a safer alternative.
  • The case discussed shows successful treatment of CARP with doxycycline after previous unsuccessful treatments for a condition mistakenly thought to be tinea versicolor.

Department of Neurology/Neuro-ophthalmology, UConn Health, Farmington, CT, USA

Article Synopsis
  • * An MRI indicated increased intracranial pressure, confirmed by a lumbar puncture showing high opening pressure, prompting medical intervention with acetazolamide and later the placement of a lumboperitoneal shunt.
  • * Unfortunately, complications arose from the shunt, resulting in even worse vision, and by the time she was seen by a specialist, she was legally blind with signs of optic nerve damage.

Article Synopsis
  • - Confluent and reticulated papillomatosis (CARP) is a rare skin condition mostly affecting adolescents and young adults, characterized by brownish, hyperkeratotic papules that merge into a reticulated pattern, primarily on the trunk, neck, and armpits.
  • - The exact cause of CARP is unclear, but it is thought to involve disordered keratinization; treatment may include systemic or topical therapies such as antibiotics, antifungals, and retinoids.
  • - A report on a 17-year-old boy suffering from CARP showed complete resolution of his skin lesions after 8 weeks of treatment with topical tretinoin, suggesting tretinoin can be an effective and

Article Synopsis
  • Prurigo pigmentosa (PP) is an inflammatory skin condition with an unknown cause that leads to itchy skin lesions.
  • A 50-year-old healthy Arab man experienced six months of persistent itchy brownish lesions on his lower back, prompting a skin biopsy that confirmed the diagnosis of PP.
  • After initial treatment with doxycycline cleared the lesions, they recurred after a year, leading to a restart of the same antibiotic treatment.

Article Synopsis
  • Confluent reticulated papillomatosis (CRP), terra-firme-forme-dermatitis (TFFD), and dermatitis neglecta (DN) are benign skin conditions that cause hyperpigmented lesions, making them difficult to distinguish and treat based on appearance alone.
  • A study of 62 patients revealed distinct dermoscopic patterns for each condition, with CRP showing a cerebriform pattern, while TFFD and DN presented patterns resembling a “mosaic” and “cornflake-like” appearance, respectively.
  • The findings suggest dermoscopy is an effective, noninvasive tool for diagnosing these similar-looking conditions, helping physicians identify them based on unique features like the color and formation of pigment globules.

Article Synopsis
  • - Confluent and reticulated papillomatosis (CRP) is a rare skin condition mainly affecting young adults, characterized by persistent brown papules and plaques, particularly in skin folds, though its exact cause is unclear.
  • - A case study of a 23-year-old man revealed symptoms like painful sensations and the development of brown macules, along with sweat test results indicating he had acquired generalized anhidrosis, which improved with treatment.
  • - Histological analysis of the affected skin showed changes like hyperkeratosis and sweat duct obstruction, suggesting potential links between the patient's hypohidrosis, reticulated lesions, and obesity-related sweat dysregulation.

Article Synopsis
  • Confluent and reticulated papillomatosis (CARP) is a skin condition that typically appears in teenagers and may be related to metabolic syndrome.
  • Previous research suggested connections between CARP and health issues like insulin resistance, type 2 diabetes, and a skin condition called acanthosis nigricans.
  • This study aims to analyze a large group of children with CARP to better understand its possible link to metabolic syndrome in the pediatric population.

Article Synopsis
  • Confluent and reticulated papillomatosis (CRP) is a skin condition that often goes undiagnosed and has an unclear cause.
  • Antibiotics are thought to be effective for CRP mainly due to their antibacterial and anti-inflammatory properties.
  • Additional treatments, like weight loss and addressing any underlying hormonal issues, may also provide relief for those affected by CRP.

Retrospective review of confluent and reticulated papillomatosis in pediatric patients.

Pediatr Dermatol

September 2021

Section of Dermatology, Department of Medicine and Pediatrics, University of Chicago Medical Center, Chicago, IL, USA.

Background/objectives: Confluent and reticulated papillomatosis is a skin condition with unclear etiology and limited understanding of risk factors, comorbidities, and treatment strategies in the pediatric population. This study aims to describe the varied presentations and outcomes of confluent and reticulated papillomatosis and report associated comorbidities in pediatric patients.

Methods: In this retrospective single-institution case-control study, pediatric patients with a diagnosis of confluent and reticulated papillomatosis seen between 2012 and 2020 were matched approximately 1:5 with an acne vulgaris cohort based on diagnosis, setting, and time period when seen.

Article Synopsis
  • Dermoscopy is gaining traction not only for diagnosing skin cancers but also for evaluating various pigmentary disorders, as recent studies have shown its effectiveness in this area.
  • A comprehensive review of literature from PubMed examined numerous pigmentary conditions, including melasma, vitiligo, and several others, to explore their unique dermoscopic features.
  • The findings suggest that dermoscopy can help clinicians differentiate between these disorders, which can be challenging to diagnose clinically and may cause significant emotional distress for patients.
