This case report describes a rare instance of alopecia neoplastica, where breast cancer metastasized to the scalp, which can be mistakenly diagnosed as alopecia areata.

This article reports a unique case of a 60-year-old woman with alopecia areata and myasthenia gravis, suggesting a rare paraneoplastic syndrome connection primarily limited to prior reports involving hematologic cancers.

This research observed that mutations in the PTCH gene are common in both sporadic and hereditary basal cell cancers, suggesting a critical role of the PTCH signaling pathway in skin tumor development.

This review discusses Graham-Little Piccardi-Lasseur syndrome, a rare dermatosis with limited treatment options, emphasizing the importance of early diagnosis through physical exam and dermoscopy, but reports no new results.

In this study using mice, simultaneous deficiencies in claudin-1 and claudin-3 were associated with hair loss and altered hair follicle architecture during the telogen phase, suggesting a role in hair retention.

This study found that Chrysanthemum zawadskii extract may promote hair growth by inducing an earlier conversion of telogen to anagen and increasing the proliferation of dermal papilla cells in mice and human hair follicle cultures.

This case report identified a 6-month-old girl with congenital generalized hypertrichosis and gingival hyperplasia, where a de novo CNV on chromosome 17q24.2-24.3 was associated with reduced expression of ABCA5 and SOX9.

In this study involving women undergoing taxane-based chemotherapy, a twice-daily topical application of BPM31543 was well-tolerated and showed potential in reducing severe hair loss, prompting further investigation at higher doses.

This study found that scalp melanoma often occurs in areas with androgenetic alopecia, and patients without alopecia might experience a later diagnosis due to hair coverage, leading to potentially worse outcomes.

This study found no significant differences in certain proinflammatory protein levels between patients with alopecia areata and healthy controls but noted a potential association between disease severity and increased atherosclerosis risk.

This study observed Malassezia hyphae in the keratotic plugs of healthy individuals, which contrasts with previous findings of these hyphae primarily in lesions of pityriasis versicolor patients.

This study found that dermoscopy of the axilla in patients with frontal fibrosing alopecia revealed significantly higher odds of brownish peripillary halos, suggesting a diagnostic clue for the condition in this region.

In this case report, researchers described a unique skin lesion in a 55-year-old woman, identifying it as folliculosebaceous cystic hamartoma with an unusual combination of spindle cell lipomatous and neural components, which had not been previously documented in such cases.

This study found that blocking the chemokine CXCL12 in a testosterone-induced mouse model of androgenetic alopecia restored hair regeneration and reduced fibrosis and immune alterations.

This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

Men with a certain type of hair loss (AGA) have higher bad cholesterol and lower good cholesterol levels, making them more likely to get heart disease.

This study found that subcutaneous injection of a CXCL12 neutralizing antibody significantly promoted hair growth in androgenic alopecia and inhibited hair loss in alopecia areata in mouse models, suggesting its potential as a promising treatment for hair loss.

In this case report, a 72-year-old female with Cronkhite-Canada syndrome showed significant improvement in symptoms and gastrointestinal polyps after hormone therapy and additional treatment.

This study undertook a retrospective chart review to examine the link between the severity of female pattern hair loss and abnormal cholesterol levels in patients from a specialty alopecia clinic, but results are not reported.

This case report describes a 68-year-old woman diagnosed with chronic cutaneous lupus, characterized by irregular plaques with distinct pigmentation and scarring alopecia, confirmed through histopathology revealing specific skin changes.

This study found that frontal fibrosing alopecia involves distinct molecular changes, such as downregulation of steroid and cholesterol pathways and upregulation of fibrotic and immune response genes, which may help guide treatment strategies.

This case report describes a patient with trichothiodystrophy presenting with autism, mental retardation, and seizures, characterized by distinct hair abnormalities under microscopy.

This study identified a genetic locus associated with rhabdomyosarcoma susceptibility in mice and found that specific differentiation markers are linked to the regression of basal cell carcinoma.

This case report examines a patient with myasthenia gravis, invasive thymoma, and paraneoplastic pemphigus associated with alopecia areata, notably without the usual mucosal involvement.

This study found that in Arabidopsis root hairs, mild chitosan treatment triggered callose deposition and slowed growth, while a higher concentration inhibited growth without callose deposition, indicating different responses based on chitosan concentration.

This study found that alopecia areata patients with a CCHCR1 gene variant had higher recurrence rates and structural abnormalities in hair compared to those without the variant.

This report is the first to associate Cronkhite-Canada syndrome with multiple myeloma, describing regenerative pseudopolyps in a 58-year-old woman rather than true adenomatous polyps.

This case report describes a patient with myasthenia gravis, alopecia, and hair follicle hamartoma, showing notable similarities to a previously reported case.

The authors concluded that thymoma-associated paraneoplastic syndrome in cats may manifest as noninflammatory alopecia instead of exfoliative dermatitis, and should be considered when diagnosing multifocal noninflammatory alopecia.

This case report describes a rare instance of trichogerminoma with unusually numerous mitotic figures and a higher Ki67 proliferative rate, distinguishing it from previously documented cases.
