INTRODUCTION: Netherton syndrome (NS) is a rare autosomal recessive genodermatosis in the group of congenital ichthyosis. The clinical manifestations of the syndrome vary from a very mild clinical manifestation occurring with the picture of ichthyosis linearis circumflexa to exfoliative erythroderma. It can be fatal in the first days of a newborn's life due to dehydration, hypothermia, weight loss, respiratory infections, and sepsis. A specific anomaly of the hair trichorrexis invaginata is considered pathognomonic for the syndrome...

INTRODUCTION: Immune checkpoint inhibitors are new drugs approved for the treatment of many types of malignancies. Despite their wide use and unquestionable clinical benefits, these agents have also been associated with a unique spectrum of side effects known as immune-related adverse events. In this study, we report the first case of atezolizumab-induced pustular psoriasis and acrodermatitis. CASE PRESENTATION: A 61-year-old woman presented to our department with erythematous-desquamative and pustular lesions involving all hands and feet fingers, inguinal region, and trunk, associated to severe psoriatic onychodystrophy...

INTRODUCTION: Scabies is a common parasitic infestation caused by the mite Sarcoptes scabiei. Scabies can mimic other entities clinically, resulting in misdiagnosis. The presence of a mite in the stratum corneum on biopsy specimens is diagnostic of scabies. However, there are instances when mites are not visible, and immunohistochemical (IHC) staining may be misleading. An example is when IHC demonstrates Cluster of Differentiation 1a and S100 positivity. The main differential diagnosis for this finding is Langerhans cell histiocytosis, a group of idiopathic disorders of bone marrow-derived Langerhans cells, with manifestations ranging from isolated to life-threatening multisystem disease...

INTRODUCTION: Mucocutaneous complications or adverse events due to SARS-CoV-2 infection or vaccination have been well delineated in the literature, respectively. Most eruptions are considered mild and self-limiting; however, for the atypical cases with a tentative clinical diagnosis, performing a biopsy and histopathological assessment is pivotal to confirm the diagnosis and subsequently prescribe a more tailored treatment. Despite the diverse reporting of such incidents globally, most studies restrict the rate of biopsied cases to less than 15%...

Hidradenitis suppurativa is a chronic inflammatory disease which affects apocrine glands and hair follicles of the skin, primarily in the axillary and groin regions. This condition can be highly debilitating, causing painful lesions and a negative psychological impact on patients. While medical and minimally invasive treatments are available, surgical intervention may be necessary for severe cases. In cases involving axillary defects, the use of local flaps such as the parascapular flap is a viable option. In this case report, we present a 34-year-old woman who presented to our clinic with a history of recurrent abscesses and cutaneous infections in the axillary region...

INTRODUCTION: Basosquamous carcinoma is an uncommon subtype of basal cell carcinoma (BCC), characterized by aggressive local growth and metastatic potential, that mainly develops on the nose, perinasal area, and ears, representing 1.2-2.7% of all head-neck keratinocyte carcinomas. Although systemic therapy with hedgehog inhibitors (HHIs) represents the first-line medical treatment in advanced BCC, to date, no standard therapy for advanced basosquamous carcinoma has been established. Herein, we reported a case series of patients affected by locally advanced basosquamous carcinomas, who were treated with HHIs...

INTRODUCTION: Bart's syndrome is an uncommon inherited congenital disorder associating congenital cutaneous aplasia of the extremities and inherited epidermolysis bullosa. Bilateral and symmetrical involvement of the limbs is exceptionally described on black skin. In most cases, the diagnosis is clinical; however, the management remains very difficult and the extended forms are a real therapeutic challenge. We report 2 cases of Bart's syndrome observed in a sub-Saharan African country (Senegal, Dakar)...

Green nail syndrome (GNS) is a persistent greenish pigmentation of the nail plate, originally described in 1944 by Goldman and Fox, due to Pseudomonas aeruginosa infection. Recently, pulmonary co-infection of P. aeruginosa and Achromobacter spp. has been described in patients with cystic fibrosis. Achromobacter xylosoxidans is a multidrug-resistant (MDR) pathogen involved in lung and soft tissue skin infections. Both Achromobacter xylosoxidans and P. aeruginosa are mainly found in humid environments or in water...

Psoriasis is a common chronic skin disease mainly located in areas of friction. Psoriasis of the lips as an exclusive presentation is rare and often misdiagnosed. Different anti-psoriatic therapies have been proposed, but the literature is limited to case studies with partial results. Biologic therapies have revolutionized the management of many dermatologic conditions, including psoriasis, and they are approved for pediatric use. We report the case of a 14-year-old boy with a 2-year history of white-yellowish scaling lesions on his lips, without intraoral involvement...

Lichen planus is a chronic inflammatory disorder that may affect the skin, nails, and/or oral mucosa. Bullous lichen planus is a rare variant of lichen planus, which is even less common in the nails. We present a case of nail bullous lichen planus, in a 48-year-old male presenting with a 10-month history of onychodystrophy of all ten fingernails. A longitudinal excision of the left thumbnail was performed, with histopathology consistent with lichen planus with focal transition to bullous lichen planus. He was treated with intralesional triamcinolone injections to the fingernails monthly, with improvements noted after three treatments...

Adverse reactions in tattooed skin during magnetic resonance imaging (MRI) are rare but well known. Previous reports describe sudden burning pain in tattooed skin, sometimes accompanied by mild erythema and oedema when entering MRI scanners. The pathophysiology remains unclear, but simple direct thermal heating can be excluded. It has been hypothesized that MRI-triggered torque and traction create neural sensations from magnetic pigment particles. However, this case enlightens yet another possible mechanism...

Poroid hidradenoma (PH) is a rare benign adnexal tumor of eccrine differentiation. It is the rarest of the four described variants of poroid neoplasms. PHs characteristically share a hybrid of the architectural features of the hidradenoma, namely, tumor cells are entirely intradermal with both solid and cystic components, and the cytologic characteristics of the poroid neoplasms, containing predominantly poroid and cuticular cells. Many published reports of PH since its original discovery in 1990 state that "very few" cases of PH can be found in the literature...

Neurofibromatosis type 1 is a genetic disorder impacting approximately 2.5 million people worldwide, often leading to development of numerous benign yet disfiguring cutaneous neurofibromas (cNF). Removal of cNF is limited to excision or laser ablation with common post-operation complications and scarring. The current case explores a new approach to removal or reduction of cNF by a minimally invasive and pain-reduced treatment modality. A 40-year-old female patient with numerous cNF across her body underwent a single treatment using a 20 MHz dermatologically focused ultrasound device on seven selected cNF on the upper back...

Spinal dysraphism (SD) refers to the abnormal fusion of dorsal midline structures during embryogenesis. It encompasses a variety of congenital spinal defects, ranging from an overt defect in which neural tissue is exposed with no overlying skin (open SD) such as myelomeningoceles to skin-covered malformations (closed or occult SD). A 13-year-old boy presented with recurrent multiple painless ulcers and erosions over the tips of the toes, mainly involving the right foot with hemorrhagic crusts for 5 years. A review of systems revealed back pain, urine incontinence, and numbness in his right knee...

Porokeratosis is a group of well-known clinically distinct entities, characterised by different clinical aspects, but sharing a single common histological aspect, namely the cornoid lamella. Usually, porokeratosis occurs in the limbs and trunk, while it rarely involves the face, especially as an exclusive, single, and solitary lesion. We report the case of a 52-year-old Caucasian woman, with an 11-month history of a 2-cm slowly growing solitary, keratotic lesion on her left cheekbone. The patient did not present other cutaneous lesions on the face, as well as in other body sites...

Linear IgA disease (LAD) is a rare autoimmune bullous disease characterized by IgA deposition in the basement membrane zone (BMZ). A 66-year-old male was treated for myelodysplastic syndrome at our hospital for 5 years, during which his condition remained stable. He visited our department because of erythema with itching, which appeared 1 year ago and gradually exacerbated with the development of blisters and erosions. During the first visit, multiple erythemas with erosions and crusts on their periphery were observed on the trunk and lower limbs...

Fungal infections can be challenging to diagnose, but doctors of every specialty may encounter this issue. They can be mistaken for other common dermatoses such as eczema or psoriasis and inadvertently be treated with topical corticosteroids or calcineurin inhibitors. This may lead to tinea incognita, a term used to describe a fungal infection with an altered clinical appearance, which may confuse the clinician even further. This case report presents a 54-year-old previously healthy man with a 4-month history of a painful and pruritic rash in the genitoinguinal region...
