Paraneoplastic or treatment-associated dermatomyositis: a diagnostic challenge
Dermatomyositis (DM) is a systemic autoimmune disorder characterized by proximal myopathy and dermatological findings. Approximately 15-30% of DM cases emerge as a paraneoplastic syndrome caused by a concomitant malignancy. Although more rare, in cancer patients DM has also been reported as a possible result of toxicity of some antineoplastic agents, such as taxanes and monoclonal antibodies. Herein, we report a 35-year-old woman with metastatic breast cancer who presented with skin lesions after initiation of paclitaxel and anti-HER2 agents. Clinical, laboratory, and histological findings were consistent with the diagnosi...

Artificial intelligence in medicine - dermatology compared to other medical specialties in FDA-cleared software as medical device
Artificial intelligence (AI) and machine learning (ML) have occupied the center stage in healthcare as research groups and institutions investigate their capabilities and risks. Dermatology is often cited as one of the medical specialties most ripe for disruption with AI technology due to the heavy incorporation of visual information into clinical decisions and treatments. Although the literature on AI in dermatology is rapidly growing, there has been a noticeable absence of mature AI solutions utilized by dermatology departments or patients. This commentary provides insight into the regulatory challenges facing AI solutio...

Mycobacterium marinum infection of the wrist
We report a patient with cutaneous Mycobacterium marinum infection with a non-pruritic erythematous plaque on his right wrist for three months. A history of exposure to contaminated freshwater two years prior was the only exposure that could be determined. Treatment with oral ciprofloxacin combined with clarithromycin produced a good outcome. (Source: Dermatology Online Journal)

A pruritic pedunculated pink nodule on the leg
Herein, we present a patient with a lipidized fibrous histiocytoma, an underrecognized variant of dermatofibroma (cutaneous fibrous histiocytoma). Our patient presented with a nodule on the ankle that showed foamy histiocytes and hyalinized collagen bundles on histology. This case highlights a classic presentation and features of lipidized fibrous histiocytoma, raising further awareness of this distinctive variant of dermatofibroma that should be distinguished from xanthoma and xanthogranuloma.

Post-zoster fibroelastolytic papulosis: an example of Wolf isotopic response
Wolf isotopic response describes the onset of a new dermatosis at the site of a previous, healed dermatosis, which is usually a herpes zoster infection. Fibroelastolytic papulosis is a poorly understood elastolytic condition defined by a loss of elastic fibers specific to the papillary dermis. The present report describes a case of fibroelastolytic papulosis with onset following herpes zoster infection. This association provides new evidence for an immunopathogenic origin for fibroelastolytic papulosis and further supports current theories of the pathogenesis of Wolf isotopic response.

Cutaneous mucormycosis involving a colostomy site
We present an immunocompromised patient with cutaneous mucormycosis that developed in a peristomal ulcer following a hemicolectomy procedure. Histopathologic evaluation was indicative of mucormycosis. Intravenous posaconazole treatment was initiated, but unfortunately, the patient's condition deteriorated and he passed away.

Lichen planus associated with secukinumab treatment for plaque psoriasis
Secukinumab and ixekizumab are IL17A inhibitors most commonly used to treat psoriasis. Common side effects include upper respiratory tract infections, injection site reactions, and mucocutaneous candidiasis. Recently, these medications have been reported to trigger lichen planus and lichenoid reactions have also been reported as an emerging side effect of biologics, especially tumor necrosis factor inhibitors. Herein, we report a patient with lichen planus that appeared after initiation of secukinumab for the treatment of psoriasis. (Source: Dermatology Online Journal)

The psychosocial impacts of vitiligo, psoriasis, and alopecia areata on pediatric patients
Children and adolescents with chronic cutaneous conditions are at risk of experiencing adverse psychosocial effects such as anxiety, depression, and loneliness. The well-being of these children's families may also be impacted by their child's condition. It is important for the quality of life of patients and their families to better understand the psychosocial impact caused by pediatric dermatologic conditions and interventions that help mitigate these effects. This review summarizes the psychological impact of the common pediatric dermatological disorders, vitiligo, psoriasis, and alopecia areata, on children and their ca...

Widespread localized areas of annular patches, plaques, and erythema
Without prompt diagnosis and treatment, patients with Lyme disease may develop life threatening multi-organ system complications. As such, we discuss the key diagnostic features of the condition along with patient-specific suggested treatment protocols. Additionally, Lyme disease is reportedly expanding to regions that were previously not impacted, key epidemiological features are outlined. We discuss a patient with severe Lyme disease who presented with widespread cutaneous involvement and atypical pathologic findings within an uncharacteristic geographic region. Erythematous, annular patches and plaques with dusky-to-cle...

Nodular lymphangitis related to methicillin-resistant staphylococcus aureus infection
Nodular lymphangitis, also known as lymphocutaneous syndrome or sporotrichoid lymphangitis, presents with inflammatory nodules along the lymphatic vessels, typically involving the upper or lower extremities. Although the most common cause of nodular lymphangitis is infection due to Sporothrix schenckii, Nocardia brasiliensis, Mycobacterium marinum, or Leishmania braziliensis, it is important for clinicians to be aware of methicillin-resistant Staphylococcus aureus as a rare cause of nodular lymphangitis and perform gram stain, bacterial culture, and antibiotic sensitivity profiles when appropriate. History of recent travel...
