This case study describes an unusual instance of separate trichoadenoma and melanocytic naevi occurring simultaneously on the face, with the cause of their association remaining uncertain.

This study found that overexpression of ornithine decarboxylase and activated Ha-ras together led to a high rate of tumor development in a mouse model without additional carcinogens.

This case report describes an unusual trichofolliculoma in a 54-year-old man, notable for its prominent mucinosis, which is typically not as abundant in such tumors.

This case report describes a unique lesion in a 10-month-old girl, characterized by increased eccrine glands and hair follicles, leading to the proposed term "hybrid eccrine gland and hair follicle hamartoma".

In this study, researchers found that overexpression of the Hedgehog signaling effector Gli2 in mice led to odontogenic keratocysts development, implicating GLI transcription factors in human keratocyst pathogenesis.

This study found that scalp basal cell carcinomas do not appear to behave more aggressively than other types, despite suggestions in the literature.

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

This paper reports a rare case of focal mucinosis in a 58-year-old woman's eyelid, initially resembling a nevus, successfully treated with surgical excision with no recurrence over a three-year follow-up.

This study reported a rare case of ovarian steroid cell tumor removal resulting in normalized hormone levels, resumption of menstruation, and subsequent spontaneous pregnancy in a 31-year-old woman.

This study presented an elderly male with a nodular lesion diagnosed as pilomatricoma and discussed the value of diagnostic tools like dermoscopy and high-frequency ultrasonography, encouraging clinicians to consider pilomatricoma in differential diagnoses of nodular lesions across all ages.

This study found that while malignant pilomatricomas maintain some keratin expression patterns seen in benign counterparts, they notably express additional epithelial keratins, potentially influencing tumor calcification.

An 81-year-old woman's severe male hormone symptoms were caused by an ovarian tumor, which was treated with surgery.

This case report details a 73-year-old woman with significant hirsutism and hair loss linked to a rare ovarian Leydig cell tumor, which was resolved by bilateral salpingo-oophorectomy, normalizing her testosterone levels and addressing her symptoms.

This case report discusses a 69-year-old woman with alopecia areata who presented with a growing lesion on her hand, raising diagnostic considerations during her appointment for scalp steroid injections.

This case report highlights the importance of timely biochemical and radiographic evaluation of adrenal masses, as illustrated by a rapidly progressing aggressive adrenal cortical carcinoma.

This case report suggests that intralesional cidofovir successfully treated SCC without systemic toxicity, making it a potential alternative to consider alongside surgical excision.

A rare benign skin tumor showed unusual features of sebaceous and sweat glands, important for correct diagnosis.

This case study reported a postmenopausal woman with a testosterone-secreting ovarian tumor that was not detected through standard clinical or radiological examination but was found via biopsy.

This article discusses ovarian steroid cell tumors, which can produce testosterone and manifest symptoms like hirsutism, emphasizing surgery as the primary treatment, but reports no new clinical findings.

This clinical case study describes an aggressive squamous cell carcinoma developing within a giant epidermal cyst on the abdomen.

This case report of a 60-year-old male patient diagnosed with trichilemmal carcinoma, initially mistaken for a sebaceous cyst, highlights the importance of careful evaluation of atypical swellings for correct diagnosis and treatment.

This case report describes a 22-year-old woman with a nevoid plaque termed localized follicular hamartoma, characterized by skin-colored papules and specific cellular and structural features.

This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.

This study found that FLCN deficiency in mice muscles led to increased mitochondrial biogenesis and a metabolic shift towards oxidative phosphorylation, with a similar advantage observed in FLCN-null kidney cancer cells.

This study found that dysregulation of the folliculin-p0071 interaction may lead to changes in cell adhesion and signaling, contributing to conditions like emphysema and renal cell carcinoma.

This review discusses recent findings on molecular changes in cutaneous adnexal tumours and reports novel markers and pathways involved, highlighting the diverse oncogenic drivers and tumour suppressor alterations.

This article discusses the kinetic and topographical heterogeneity in follicular thyroid neoplasms and reports no new research findings; the authors emphasize understanding diverse growth patterns.
