This review outlines the diverse clinical presentations of cutaneous metastases in breast cancer patients and emphasizes the importance of biopsy for accurate diagnosis, but reports no new results.

This study reports that in ovarian high-grade serous carcinoma, overexpressed S100A4 likely promotes epithelial-mesenchymal transition and cancer stem cell properties, affecting tumor behavior through its interaction with NMIIA and mutant p53.

This report describes a pancreatic mixed acinar-neuroendocrine carcinoma in a cat, underscoring its diagnostic complexity and the need to consider it in diagnoses of pancreatic masses with mixed features.

This systematic review found that mixed epithelial and stromal tumor of the seminal vesicle (MESTSV) is characterized by abundant stromal proliferation, architectural heterogeneity, and strong immunoreactivity for ER/PR, with most being benign but warranting surveillance for possible recurrence or metastasis.

This review discusses steroid cell tumors of the ovary, their hormone production, symptoms, and evaluation, emphasizing surgery as the key treatment approach; it reports no new clinical results.

This study retrospectively analyzed 945 patients with head and neck cSCC to identify risk factors for recurrences, reporting treatment modality, tumor characteristics, and patient factors such as immunosuppression as strong predictors for loco-regional recurrences.

This study investigated pilomatrixoma, a benign skin tumor, and found that irregular expression of β-catenin and Lef-1 in transitional cells may contribute to amorphous debris and cyst formation.

This case report presents a rare instance of recurrent ACTH-independent Cushing’s syndrome due to PBMAH, coinciding with the development of a pheochromocytoma, highlighting the need for thorough reevaluation in similar recurring cases.

This study reported that squamous cell carcinomas of the scalp can become extraordinarily aggressive, highlighting the need for early diagnosis and careful use of treatment strategies like wide excision and radiation therapy.

This study suggests that the adrenal gland may contribute to prostate cancer treatment resistance and indicates potential steroid production or dependency in ovarian cancer.

This report describes the sonographic characteristics of a proliferating trichilemmal tumor in the subungual region, identifying it as a heterogeneous mass with echogenic foci, potentially representing keratin and cholesterol.

TICE salvage chemotherapy is effective for treating germ-cell tumors with poor prognosis.

This case report describes a pilomatricoma in a 21-year-old woman, highlighting the diagnostic process and illustrating the potential for intraoral surgical access to minimize scarring.

This study observed that calcifying epithelioma of Malherbe is composed of tumor cells that differentiate into both hair cortex and outer root sheath, supporting its hair follicle origin.

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 study reported that squamous cell carcinomas of the scalp can be extraordinarily aggressive, potentially metastasizing and causing death, highlighting the need for early diagnosis and careful treatment approaches.

This case report suggests that ovarian steroid cell tumors should be considered in postmenopausal women with hirsutism and elevated testosterone, with surgery being effective in resolving symptoms and preventing recurrence.

This case report emphasizes the need to consider Sertoli-Leydig cell tumors in the differential diagnosis of adnexal masses in patients with Peutz-Jeghers syndrome, noting that these tumors can present unusually with bilateral adnexal involvement.

This case report describes a trichofolliculoma with perineural invasion, highlighting a rare and clinically significant finding in a typically benign hair follicle tumor.

In this case report, a patient with Cronkhite-Canada Syndrome developed colon cancer and liver metastasis despite hormone therapy, highlighting the need for regular monitoring and early detection strategies.

This case study highlights that breast cancer may present as alopecia refractory to usual treatments, indicating the need for consideration of underlying malignancy in such cases.

This case report describes a 20-month-old female with a rare adrenocortical virilizing tumor, successfully treated with surgery, showing no pathological lesions over a 10-year follow-up.

This study found that human basal cell and squamous cell carcinomas have distinct gene expression patterns, with specific up-regulation of zinc finger encoding genes in basal cell carcinoma.

This case study highlights the aggressive progression and complex management challenges of metastatic insulinomas, with an emphasis on considering early systemic chemotherapy and advanced therapies like everolimus and PRRT for improved outcomes.

In this study, Brca1(S971A/S971A) mice showed a moderately increased risk of spontaneous tumor formation and defects in DNA damage response, suggesting CHK2 phosphorylation of BRCA1 is crucial for tumor suppression.

This study reports that Mohs micrographic surgery resulted in no recurrences of pilomatrix carcinoma, compared to a 34.5% recurrence rate with traditional surgical excision.

This study found that nevoid basal cell carcinomas originate in the epidermis and the upper part of the hair follicle, showing similarities to nonnevoid basal cell carcinomas.

This case study describes a middle-aged woman diagnosed with a proliferating trichilemmal tumor on her scalp, emphasizing the importance of comprehensive diagnostic approaches and highlighting surgical excision as the primary treatment.

This case study found that a 1.6cm ovarian Leydig cell tumor, causing hyperandrogenism in a postmenopausal woman, evaded detection on standard imaging techniques, underscoring the difficulty of diagnosing such tumors with imaging alone.
