This case report describes a patient with SLE and APLS who developed basaloid follicular hamartomas, which persisted despite aggressive treatment for SLE, although hair regrowth occurred.

This case report describes a 70-year-old kidney transplant recipient who developed a keratoacanthoma near an arteriovenous fistula after returning to hemodialysis and stopping immunosuppression.

This report describes a rare case of angiokeratomas on both the upper eyelids and scrotum, adding to the limited literature on eyelid occurrences and discussing potential causes.

This study reported that alopecic lesions after radiation exposure during angioembolization share dermoscopic features with alopecia areata, highlighting the importance of accurate patient history to avoid misdiagnosis.

This case study suggests that thrombosis was related to anti-phospholipid antibody in a woman with systemic lupus erythematosus, characterized by multiple aseptic bone necroses and arterial blockages.

This report describes a case where rituximab provided durable remission in a patient with refractory aggressive diffuse B-cell lymphoma that was unresponsive to prior chemotherapy.

This case report describes a woman with systemic lupus erythematosus who developed both pneumonitis and nephritis, with identical immune complexes found in her lungs and kidneys, suggesting a common pathogenetic mechanism.

Long-standing benign tumors can become cancerous, especially in people with weakened immune systems.

This report discusses a potentially underdiagnosed form of multisystem Langerhans cell histiocytosis in infants, demonstrating the use of thymic sonography for staging, highlighting a case where thymic and cutaneous involvement was confirmed, and suggesting thymic ultrasound may aid in better diagnosis and management of LCH.

This study observed that cutaneous lymphocytosis in cats is a slowly progressive and relatively benign disease, but predicting individual clinical outcomes from skin lesions was not possible.

This abstract discusses the importance of controlling visible abdominal tumors in women with ovarian cancer to improve survival, and notes that nonvisible microscopic tumors are then targeted with chemotherapy; it reports no new results.

Examining more lymph nodes can improve survival rates in breast cancer patients without lymph node involvement.

This study found that low-dose chemotherapy for solitary bone lesions of Langerhans cell histiocytosis in children led to quicker recovery, higher quality of life at 3 months, and was more cost-effective compared to surgery.

A rare skin growth was successfully removed without recurrence after one year.

This study analyzing 40 pediatric patients treated for head and neck sarcomas in a Polish clinic from 2015-2022 found rhabdomyosarcoma was the most common type, requiring complex oncological and surgical treatment, often involving reconstructive techniques.

An elderly man with skin amyloidosis and abnormal blood proteins was monitored without finding widespread disease after 18 months.

In this literature review, researchers reported that sentinel lymph node mapping appears safe and effective for early stage ovarian cancer patients, potentially reducing unnecessary lymph node dissections, though it is not yet standard practice, necessitating further studies.

This article reviews the distinctive features of cutaneous lymphadenoma, a variant of trichoblastoma, and its differential diagnosis, but it presents no new empirical results.

Two cases of a rare skin condition were successfully treated with laser therapy, offering a non-surgical treatment option.

This article discusses the potential of intralesional cidofovir for treating SCC without systemic toxicity, noting that surgical excision remains the best treatment option; it reports no new clinical results.

This letter to the editor reports that sentinel lymph node status is the strongest independent predictor for both disease-free and overall survival in patients with thick melanoma.
