Unveiling the Unusual: A Unique Case of Verrucous Cyst.

Verrucous cysts are uncommon types that cannot be distinguished from epidermal inclusion cysts clinically and require histopathological analysis and human papillomavirus (HPV) polymerase chain reaction (PCR) for accurate diagnosis. The pathogenesis of verrucous cysts is thought to involve HPV infection, either of an existing cyst or through direct infection of keratinocytes, leading to new cyst formation. While verrucous cysts can affect individuals of any sex and are typically found on the trunk, extremities, and face, they are particularly notable for their potential association with high-risk HPV types, such as 16 and 18, which may lead to malignant transformation. In this report, we present the case of a 48-year-old female with a history of endometriosis and pelvic inflammatory disease, who sought evaluation for a persistent subcutaneous nodule on her right flank. The patient reported pain, a recent color change, and an increase in the nodule size. Clinical examination revealed a 2.7 cm subcutaneous nodule with a central brown-gray papule. Despite no history of dermatologic malignancies, the nodule was excised, and subsequent histopathological examination confirmed a diagnosis of a ruptured verrucous cyst. The cyst exhibited acanthotic papillomatous squamous epithelium without cytologic atypia and koilocytic change in cells. This case offers direct and valuable insights into the clinical presentation, diagnosis, and management of verrucous cysts. It highlights the importance of a thorough diagnostic approach, combining histopathological examination with HPV PCR testing, to accurately differentiate verrucous cysts from other similar cutaneous lesions. The report also emphasizes the need for vigilance in managing these cysts due to their potential association with high-risk HPV types and the consequent risk of malignant transformation. These insights contribute significantly to the existing body of literature on verrucous cysts and aim to enhance clinical awareness and patient care in dermatology.

Prayer-Related Dermatoses in Muslims.

Prayer rituals are an integral part of the daily lives of Muslims worldwide. This comprehensive review aims to explore the common dermatoses associated with prayer among Muslims and provide insights for dermatologists to facilitate accurate diagnosis and reduce unnecessary investigations. A systematic literature search returned 367 published articles, of which 21 met the inclusion criteria. Friction-induced dermatitis was the most frequently reported dermatosis, primarily affecting the forehead, knees, dorsum of the feet, and lateral malleoli. Friction-related marks often present as hyperpigmented lichenified plaques, and are more common in elderly individuals and males. Cases of contact dermatitis and fungal infections were also reported. Allergic contact dermatitis was linked to perfume application before Friday prayers, whereas fungal infections were attributed to increased water retention between toe webs, possibly related to communal ablution and prayer areas. Awareness of these prayer-related dermatoses enables dermatologists to provide holistic care for diverse populations and targeting specific interventions with respect for patients' religious beliefs. For example, Muslim patients with symptomatic frictional dermatoses may benefit from use of padded prayer rugs, especially diabetic patients whose lesions carry an increased risk of progressing to neuropathic ulcers.

A Case of Herpes Zoster Ophthalmicus in a Recently Transplanted Renal Patient.

Herpes Zoster Ophthalmicus (HZO) is a common manifestation of the reactivated Varicella Zoster virus, primarily affecting the eye and trigeminal nerve. This case study presents the clinical course of a 51-year-old male who underwent a renal transplant due to end-stage renal disease, further complicating the management of HZO. The patient's medical history also includes hypertension, type 2 diabetes mellitus, chronic kidney disease (CKD), cerebrovascular accident (CVA), and retinal detachment. Upon examination, the diagnosis of HZO was confirmed based on the presence of a characteristic unilateral vesicular rash in the V1 cranial nerve dermatomal distribution, accompanied by ophthalmic symptoms such as eyelid swelling and visual impairment. Given the patient's immunosuppressive regimen post-transplant, intravenous acyclovir was initiated for antiviral therapy, while supportive care was provided for pain control. Notably, the patient experienced a subsequent decrease in pain intensity and improvement in the vesicular rash. This case highlights the challenges in managing HZO in patients with a history of renal transplant and multiple comorbidities, emphasizing the importance of tailored treatment strategies to optimize patient outcomes. Further research is warranted to better understand the impact of immunosuppression and comorbidities on the course and management of HZO in this population.

IgA Vasculitis Associated With COVID-19.

IgA vasculitis, also known as Henoch-Schonlein Purpura (HSP), is an inflammatory disorder of small blood vessels that can present with palpable purpura, arthralgias, abdominal pain, and kidney disease. It is most commonly found in pediatric patients after an inciting infection but has been seen across all ages and associated with certain drugs and vaccines. COVID-19 has been associated with various cutaneous manifestations, but HSP is a rarely reported one. We present a case of a 21-year-old female presenting with a petechial rash found to be seronegative IgA vasculitis presenting concurrently with dyspnea secondary to COVID-19. She was initially seen by an outside practitioner, tested negative for COVID, and was prescribed a course of oral prednisone. Shortly thereafter, she visited the ED for worsening shortness of breath and tested positive for COVID-19, for which she received Paxlovid. Biopsy after a visit to a dermatologist confirmed intramural IgA deposition on immunofluorescence, and she was tapered off prednisone and started on azathioprine.

Alopecia syphilitica, from diagnosis to treatment.

Alopecia syphilitica (AS) is an uncommon manifestation of secondary syphilis, with a prevalence that ranges from 3% to 7%. It is a nonscarring alopecia that can present in a diffuse pattern, a moth-eaten pattern, or a mixed subtype. Due to its low prevalence and similar presentation to other forms of alopecia such as alopecia areata, telogen effluvium, and tinea capitis, dermatologists must maintain a high degree of suspicion for prompt diagnosis. The diagnosis of AS is made by eliciting the patient's history, obtaining serologic tests, and examining histopathologic or dermatoscopic findings. First-line treatment includes benzathine penicillin G injection, which leads to hair regrowth weeks to months after administration. In this article, we present a focused review on the diagnosis of AS and discuss evidence-based therapeutic approaches for the management and treatment of this condition.

Janus Kinase and Tyrosine Kinase Inhibitors in Dermatology: A Review of Their Utilization, Safety Profile and Future Applications.

Janus kinase inhibitors, also commonly referred to as JAK inhibitors, are a novel drug class that target and block cytokine signaling mediated by the Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway, thereby regulating immune response and cell growth. Although JAK inhibitors are mainly used for rheumatological conditions such as rheumatoid arthritis, their application in the field of dermatology is actively being investigated. Tofacitinib is US FDA-approved for psoriatic arthritis and showing promise for treating psoriasis. Most recently, regulatory approvals for the US were gained by ruxolitinib as a first-inclass, selective, topical therapy for atopic dermatitis and oral upadacitinib for active psoriatic psoriasis. Additionally, abrocitinib and upadacitinib have demonstrated efficacy in atopic dermatitis and are pending FDA approval for this indication. The therapeutic potential of JAK inhibitors in dermatological conditions such as alopecia areata, psoriasis, atopic dermatitis, vitiligo, and dermatomyositis are showing promising results in clinical trials. Adverse events for JAK inhibitors seem to be similar to that of biologic drugs. Common adverse effects include increased risk of infections and thromboembolic events. Further investigation is needed to not only better understand the safety profile of JAK inhibitors, but also their full utility within the field of dermatology.

Acute inflammatory edema as a variant of pseudocellulitis resolved after transcatheter aortic valve implantation.

Acute inflammatory edema is a noninfectious inflammatory condition of the skin that is commonly seen in critically ill patients. It is characterized by edematous, erythematous, and nontender plaques involving the abdomen and thighs, sparing areas of the skin subject to pressure. Risk factors include fluid overload, hypoalbuminemia, and obesity. Differentiating acute inflammatory edema from cellulitis can be challenging. Supportive care is the mainstay therapy for acute inflammatory edema, with interventions primarily focused on lowering the fluid burden. We report an unusual case of a nonobese patient in the outpatient setting with acute inflammatory edema.

Vulvar syringomas.

Syringomas on the vulvar skin are relatively rare and generally bilateral. They are usually asymptomatic but can be symptomatic, with vulvar discomfort, burning, and/or pruritus. Management options include topical steroids, topical retinoids, and oral antihistamines. Cases refractory to conservative treatment may require procedural intervention, such as cryotherapy, excision, or electrosurgery. Here we describe a case of symptomatic vulvar syringomas refractory to medical management that were successfully treated with electrodessication and curettage.
