Evaluation of T ‐lymphocyte subpopulations in actinic keratosis, in situ and invasive squamous cell carcinoma of the skin
ConclusionsT‐cells and cytotoxic T‐cells progressively increase in cutaneous squamous cell carcinogenesis, while Treg counts diminish in inSCC. The K‐M score is an appropriate, easily applicable TIL scoring system in cutaneous inSCC. (Source: Journal of Cutaneous Pathology)

FOSB immunoreactivity in endothelia of epithelioid hemangioma (angiolymphoid hyperplasia with eosinophilia)
ConclusionsFOSB immunohistochemistry is sensitive in the diagnosis of EH‐ALHE, and allows differentiation from its histological mimics. An immunohistochemical panel including not only pan‐cytokeratin AE1/AE3 and endothelial markers, but also FOSB, helps in the diagnosis of epithelioid vascular tumors.

A case of radiation ‐induced osteosarcoma of the skull presenting as a cutaneous epidermotropic tumor with a short latent period
We report a case of a 34‐year‐old female who developed an osteosarcoma of the scalp, over a previous craniotomy scar, 3 years after excision of a frontal anaplastic oligodendroglioma which had been followed by a course of 6 weeks radiotherapy (58 Gy) and 6 cycles of temozolomide. The histological features were those of a high‐grade osteosarcoma with epidermotropism of tumor cells. Lymph nodes were partially replaced by high‐grade metastatic osteosarcoma, with extra‐nodal lymphatic tumor thrombi. To our knowledge the only other case report of post‐radiation osteosarcoma with a short latency period ...

GATA3 staining in primary cutaneous apocrine cribriform carcinoma: Usefulness to differentiate it from breast cancer metastasis
ConclusionEven though GATA3 expression has been reported in many benign and malignant adnexal tumors (mostly of sebaceous, follicular, and apocrine differentiation), as well as in many other neoplasms, GATA3 staining to differentiate PCACC from skin breast cancer metastasis has a high negative predictive value. A positive GATA3 staining in this context should permit one to rule out PCACC with a high level of confidence. (Source: Journal of Cutaneous Pathology)

Tumor ‐stage mycosis fungoides in palmoplantar localization with large cell transformation and partial CD30 expression shows complete response to brentuximab vedotin
Mycosis fungoides in palmoplantar localization (MFPP) is a rare variant of MF that is confined to the hands and feet. Patients commonly receive treatment over many years for suspected palmoplantar dermatitis before the diagnosis is made. Most MFPP patients remain at patch or plaque stage, and often respond to treatment with radiotherapy. Herein we describe a 77‐year‐old man who suffered 6 years of hand and foot dermatitis that failed multiple treatments, most notably TNF‐α inhibitors and mycophenolate mofetil. He eventually developed a tumor on the hand, which was biopsied to reveal a dense dermal infiltrate of...

Cutaneous squamous cell carcinoma with epidermodysplasia verruciformis ‐like features in a patient with Schimke immune‐osseous dysplasia (SIOD)
Schimke immune‐osseous dysplasia1 (SIOD) is an autosomal recessive disorder caused by mutations in the SMARCAL1 gene encoding an ATP‐driven annealing helicase that stabilizes stalled replication forks and facilitates DNA repair during replication2. The syndrome is characterized by spondyloepiphyseal dysplasia, steroid‐resistant nephropathy and cellular immune deficiency. (Source: Journal of Cutaneous Pathology)

Intravesicular taxane ‐induced dermatotoxicity in a 78‐year‐old man with urothelial carcinoma and primary cutaneous anaplastic large cell lymphoma
Patients treated with intravesical bacillus Calmette‐Guerin therapy for urothelial carcinoma often become refractory and experience recurrent disease, thus necessitating alternative intravesical treatment modalities if the patient is to be spared the morbidities associated with radical cystectomy. Intravesical treatment with taxane‐based chemotherapy, such as docetaxel, has gained traction in urologic oncology, proving to be an effective salvage therapy in such patients. Systemic taxane‐based chemotherapeutic regimens have long been used in several advanced malignancies, and their systemic side effects and associated...

How to take better photomicrographs: a step ‐wise approach

Colliding, Colonizing, or Combining?: Four Cases Illustrating the Unique Challenges of Melanoma arising in conjunction with Basal Cell Carcinoma
We present 4 tumors of melanoma co‐existing with basal cell carcinoma and discuss relevant literature regarding these biphasic entities. Patients consisted of 3 males and 1 female, ranging in age from 62–93, with lesions located on the shoulder, frontal scalp, forearm, and nose. Three of four lesions demonstrated melanoma cells limited to basal cell carcinoma tumor lobules, without evidence of direct dermal invasion by melanoma cells, raising question of whether or not these tumors should be classified as in situ or invasive melanoma. These cases highlight the complexity that such lesions pose to dermatopathologist...
