Both treatment regimens effectively improved melasma pigmentation and QoL. Either 5% cysteamine with ectoine or 4% hydroquinone with ectoine can be considered viable treatment options for melasma.

Basal cell carcinoma (BCC) of the upper lip poses significant reconstructive challenges due to the need to restore both function and aesthetics in a highly visible area. This case series presents four patients with upper lip BCC that underwent Mohs micrographic surgery followed by individualized local flap reconstruction. Flap selection was tailored to each defect, utilizing rotational, advancement, O-to-Z, and transpositional flaps to address variations in size, location, and tissue availability. All patients experienced satisfactory healing, restoration of lip contour, and preservation of oral competence, with no major complications or recurrences during follow-up. These results highlight the importance of careful preoperative planning and personalized surgical approaches in achieving optimal outcomes for upper lip reconstruction. Our findings support the use of versatile local flaps as effective options for managing complex upper lip defects following BCC excision.

Combined enzyme therapy is an effective, safe, minimally invasive, innovative approach for the treatment of foreign body granulomas.

Monkeypox virus (MPXV), originally endemic in West Africa (Clade II) and Central Africa (Clade I), has recently emerged worldwide and has reinforced the need for rapid and accurate MPXV diagnostics. This review presents and critically discusses the range of virological methods for laboratory diagnosis and characterization of MPXV as well as related lessons learned and practical experience gained from the 2022 Mpox global outbreak. Real-time PCR is currently considered the diagnostic gold standard and ensures accurate and timely confirmation of suspected Mpox cases based on suspicious skin lesions, and digital PCR improves the precision of MPXV DNA quantification. Whole genome sequencing reveals the diversity within the Clade IIb outbreak and highlights the role of microevolution in the adaptation of the virus to the human host. Continuous genomic surveillance is important for better understanding of human-to-human transmission and prevention of the emergence of variola virus-like strains. Traditional virological methods such as electron microscopy and virus isolation remain essential for comprehensive virus characterization, particularly in the context of vaccine and antiviral drug development. Despite the current challenges, serological tests detecting a range of anti-MPXV antibodies are important adjunct diagnostic and research tools for confirmation of late-presenting or asymptomatic MPXV cases, contact tracing, epidemiological studies, seroepidemiological surveys, and better understanding of the role of IgG and neutralizing antibodies in the immune response to infection and vaccination. A multidisciplinary approach combining advanced molecular techniques with traditional virological methods is important for rapid and reliable diagnosis, surveillance, and control of the outbreak.

The emergence of de novo or recurrent cutaneous eruptions in individuals with hematological diseases presents a challenge when determining whether they indicate secondary dissemination or an unrelated diagnosis. Eosinophilic eruption of hematoproliferative disease is a rare nonspecific manifestation accompanying lymphoproliferative disorders, including chronic lymphocytic leukemia (CLL). We present the case of a 70-year-old man with CLL in remission (previously treated with two 6-month cycles of fludarabine-cyclophosphamide plus rituximab, 2 and 5 years earlier) with an acute, disseminated polymorphic skin eruption. Skin biopsies from two sites (bulla and infiltrated nodule) were taken for histopathological examination. The pathologist reported giant spongiform vesicle formation with eosinophils with dermal and hypodermal inflammatory infiltrate composed of lymphocytes (predominantly T cells, fewer B cells) and eosinophils. Secondary neoplasm dissemination and sarcoidosis were excluded by means of immunohistochemistry. A diagnosis of eosinophilic eruption of hematoproliferative disease in the CLL patient post-chemotherapy and without active disease was established. Two weeks after skin remission, the patient worsened with enlarged lymph nodes and a leukocyte count of 291 × 10^9/l. CLL relapse was confirmed. Leukocytapheresis was performed and ibrutinib 140 mg three times daily was prescribed. Our case underscores the importance of recognizing this relatively common but underreported eosinophilic eruption associated with hematoproliferative diseases.

A relationship between positivity to celiac disease antibodies and psoriasis, particularly with regard to AGA, has been identified. Further studies are required to elucidate the nature, pathophysiology, and significance of these findings.

Although the serological findings were higher when compared to certain studies and quite low when compared to others, it would be beneficial to evaluate all patients with AGWs for other sexually transmitted infections.
