A Case Report and Literature Review of Bilateral Cervical Chondrocutaneous Branchial Remnants
Chondrocutaneous branchial remnants (CCBRs) are rare congenital heterotopic tissue formations originating from the first or second embryonic branchial arches. Clinically, CCBRs are characterized predominantly by unilateral and solitary cartilaginous nodules found on the lower neck region. Herein, we present a case of CCBRs in a 9-year-old male patient who presented with horn-shaped projecting masses on either side of the anterior border of the sternocleidomastoid muscle. The pathological report following surgical resection revealed that the lesion was located in the dermis and consisted primarily of hyaline cartilage tissue enclosed by a fibrous capsule, with few local vascular proliferations. Based on the clinical and pathological features, the patient was ultimately diagnosed with congenital bilateral cervical chondrocutaneous branchial remnants.
LEOPARD Syndrome with a Sporadic PTPN11 Mutation in a Saudi Patient
LEOPARD syndrome (LS) is a rare autosomal dominant inherited or sporadic genetic disorder caused commonly by missense mutations in the protein-tyrosine phosphatase-nonreceptor type 11 (PTPN11) gene. Due to its rarity and a high chance of misdiagnosis, the epidemiological profile of LS is poorly established. To the best of our knowledge, this is the second report with a documented PTPN11 gene mutation in Saudi Arabia.
A Case for Doxycycline as an Effective Treatment for Confluent and Reticulated Papillomatosis (CARP)
Confluent and reticulated papillomatosis (CARP) is a rare keratinization disorder that presents with asymptomatic, reticulated papules coalescing into plaques, which adversely affect, most often, young black persons. Minocycline is considered the drug of choice, but it is not without its host of potential side effects, including drug hypersensitivity, drug-induced lupus/vasculitis/hepatitis, blue-gray skin hyperpigmentation, acute eosinophilic pneumonia, pseudotumor cerebri, and vestibular instability, among others. Alternatively, doxycycline might be considered as another first-line agent for CARP as it can effectively clear lesions while offering a more favorable side effect profile in select patients. Herein, we present a case of CARP successfully resolved with doxycycline after a protracted treatment history of topical and oral antifungal medications for suspected tinea versicolor (TV).
Metformin-Induced Generalized Bullous Fixed-Drug Eruption with a Positive Dechallenge-Rechallenge Test: A Case Report and Literature Review
Metformin is a commonly used medication in diabetic patients. It can cause different complications including cutaneous adverse reactions. Metformin-induced fixed-drug eruption (FDE) has been reported in limited cases. Due to the popularity of metformin, clinicians need to be aware of uncommon drug reactions for proper diagnosis and treatment. Herein, we report a 43-year-old man with generalized bullous lesions with a positive dechallenge-rechallenge test diagnosed as metformin-induced generalized bullous fixed-drug eruption. Metformin dosage was stopped and lesions were treated with topical clobetasol propionate and oral prednisolone and cyclosporine-A. After a 6-month follow-up, he was well without any relapsing episodes.
Comprehensive Management of Acute Ischemic Stroke in Psoriatic Patient
Background. Stroke is one of the top causes of death and disability in several nations. Patients with psoriasis are susceptible to multiple comorbidities, including stroke. In addition to acute ischemic stroke, psoriasis and chronic inflammation require comprehensive treatment. Here, we present a comprehensive management case of a patient with an acute ischemic stroke and psoriasis. Case Presentation. A 42-year-old man came to the emergency department complaining of sudden left-sided weakness that started two and a half hours before being admitted to the hospital. The patient was treated with cyclosporine from 2013 to 2019 for a history of psoriasis. The patient was then treated for secondary stroke prevention using aspirin, vitamin B6, vitamin B12, folic acid, simvastatin, cyclosporine, and topical treatment. After two days of treatment, the patient’s condition improved clinically, and he was discharged without further neurological deficits. As a home medication, the patient’s cyclosporine was switched to the initial dose of methotrexate (7.5 mg/week) and titrated weekly to a response dose of 10 mg in the 10th week. After three months of follow-up, the patient’s condition remained stable, devoid of similar symptoms or sequelae. Conclusions. Cyclosporine should only be used for a maximum of 1 year for stroke management with psoriasis and be substituted for other systemic agents such as methotrexate. In addition, anticoagulants, antihypertensive, antihyperlipidemic, vitamin B6, vitamin 12, and folic acid regimens are highly recommended for comprehensive therapy of cardiovascular comorbidities.
Confluent and Reticulated Papillomatosis Successfully Treated with Topical Vitamin A Derivative
Confluent and reticulated papillomatosis (CARP) is a rare dermatosis that typically develops in adolescents and young adults. Clinical characteristics include hyperkeratotic papules that coalesce centrally with a reticulated pattern peripherally on the central and upper trunk, neck, and axilla. Its etiology is not precisely known, and disordered keratinization has been postulated as one of the etiologies. Treatment options of the disease include systemic (such as antibiotics, antifungals, and retinoids) and topical treatments (such as lactic acid, antifungals, retinoids, salicylic acid, urea, tacrolimus, and vitamin D analogs). We report a case of a 17-year-old boy, otherwise healthy, presented with a new onset of asymptomatic, persistent, and slowly progressing brownish skin lesions over the trunk for 6 months. The diagnosis was revised to CARP based on clinical and histopathological examination. Treatment with topical tretinoin 0.025% cream once daily was begun. There was complete resolution of his lesions at the end of 8 weeks of therapy. There has been no relapse at 2 months follow-up. The effectiveness of tretinoin in this patient supports the theory that CARP is a keratinization disorder. Initiating treatment with topical tretinoin when no limitations for its use would be reasonable as it can provide a safer alternative to systemic therapy.
