Generalized Pustular Psoriasis Flare-Up after Both Doses of BBIBP-CorV Vaccination in a Patient under Adalimumab Treatment: A Case Report
Generalized pustular psoriasis is a possibly serious condition that can be triggered by various factors. Previous studies show a slight likelihood of disease exacerbation subsequent to COVID-19 vaccination. Here, we present the first (to the best of our knowledge) case of pustular psoriasis flare after each one of the two shots of the BBIBP-CorV (Sinopharm) vaccine despite adalimumab treatment.Case Rep Dermatol 2023;15:61 –65 (Source: Case Reports in Dermatology)

Diagnostic Utility of TUNEL Staining for Degenerative Keratoacanthoma Requiring Pathologic Differentiation from Seborrheic Keratosis
Tumors developed in 2 old women presented with pathological findings similar to seborrheic keratosis, although the clinical feature of tumor showed typical keratoacanthoma. In addition to these two cases, we compared the pathological findings of a total of four cases, one case each of keratoacanthoma and seborrheic keratosis, which were clinically and histopathological typical. These two cases and the typical keratoacanthoma showed cell apoptosis by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining and infiltration of cytotoxic T cells. The keratoacanthoma in the decompensated stage may be histo...

Acral Fibrochondromyxoid Tumor Presenting as Enlarging Nodule Involving the Distal Fingertip and Hyponychium: A Case Report
In this report, we describe a case of a 39-year-old male who presented with a painful enlarging mass involving the distal right 3rd finger and hyponychium. Punch biopsy was performed and the lesion was identified as an acral fibrochondromyxoid tumor on microscopic examination. X-ray showed no bony involvement. The tumor was successfully excised with complete resolution of pain symptoms. We discuss the clinical features and immunohistochemistry findings of our case in the context of the current limited knowledge about this very rare tumor.Case Rep Dermatol 2023;15:56 –61 (Source: Case Reports in Dermatology)

Idiopathic Acroosteolysis: A Novel Cutaneous Sign Can Help Identify the Condition Early
Acroosteolysis (AO) is a rare condition characterized by resorption of the distal phalanges of the fingers and/or toes. It can be familial, idiopathic (IAO), occupational, or secondary. Other authors suggest a classification into primary (genetic disorders, lysosomal storage disorders) or secondary AO. Various skin and nail changes have been reported in this condition. However, the cutaneous change on the affected digit(s)/toe(s) during the natural course of AO has been poorly documented. A 5-year-old girl presented with a 3-month history of a distinct transverse boundary between normal skin proximally and affected crusted...

Eosinophilic Fasciitis Presenting as an Ichthyosiform Eruption of the Bilateral Ankles
Eosinophilic fasciitis (EF) is a rare connective tissue disease which closely resembles other scleroderma-like diseases. EF presents with painful swelling and hardening of the distal limbs and is often preceded by a history of strenuous exercise. The marked fascial fibrosis in EF can lead to joint contractures and causes significant morbidity in affected individuals. The authors present a rare case of EF presenting as an ichthyosiform eruption of the bilateral ankles with gradual improvement after the implementation of oral prednisone, hydroxychloroquine, and methotrexate.Case Rep Dermatol 2023;15:45 –50 (Source: Case Re...

Cutaneous Manifestations of Sarcoidosis Seen in a Patient with a History of Tuberous Sclerosis
This case report details a patient with a history of tuberous sclerosis presenting with new-onset cutaneous lesions that turn out to be sarcoidosis. There may be a shared dysfunction of mTOR present in sarcoidosis and tuberous sclerosis. As a dermatologist, it is worth understanding the cutaneous manifestations of both diseases and maintaining a wide differential when new lesions arise in a patient with a history of either disorder.Case Rep Dermatol 2023;15:40 –44 (Source: Case Reports in Dermatology)

Advanced Squamous Cell Carcinoma Developed on Chronic Hidradenitis Suppurativa, Successfully Treated with Cemiplimab: A Case Report
Hidradenitis suppurativa (HS) is an inflammatory skin disease showing a chronic-remitting course. It has been rarely reported that long-term inflammation in HS could lead to serious complications like cutaneous squamous cell carcinoma. Cemiplimab is a fully human antibody immunotherapy that inhibits programmed cell death protein-1, approved for the treatment of locally advanced squamous cell carcinoma, or metastatic squamous cell carcinoma, in patients not eligible for curative surgery or radiotherapy. Herein, we report the case of a 56-year-old patient developing an invasive SCC on longstanding and unresponsive HS lesions...

Pool Toes: A Case Report
Pool toes, a sport-related dermatosis, are caused by mechanical friction and water exposure, resulting in a special variant of irritant contact dermatitis. It is common in children, often misdiagnosed, and rarely reported. Here we report a case of a 7-year-old girl who developed this unusual type of frictional dermatitis; a pool toes diagnosis has been made. With topical corticosteroids, favorable results have been achieved. The recovery and healing process will be facilitated if one is aware of the underlying causes of such dermatitis and ceases the triggering factors.Case Rep Dermatol 2023;15:31 –34 (Source: Case Reports in Dermatology)
