Basal Cell Carcinomas

Basal cell carcinomas of prostate (BCCP) are very rare. Most arise in the transition zone and thus are associated with lower urinary tract symptoms and rarely associated with elevated prostate-specific antigen (PSA). These features make diagnosis/early diagnosis difficult because of the routine protocols followed. Basal cell carcinomas have distinctive histopathological, immunohistochemical, and to some extent also different molecular characteristics. Basal cell carcinoma in situ (BCCIS) is a nonexistent histological lesion as per the current literature, but here is an attempt to describe it through this case. A 74-year-old man presented with hematuria and previous diagnosis of prostatic hyperplasia. Based on this history, he underwent a prostatectomy ad modum Freyer. Pathological examination surprisingly revealed a diffusely infiltrative tumor with nonacinar adenocarcinoma morphology and many glandular structures probably representing BCCIS. Tumor was diagnosed as BCCP. Patient presented with metastasis to the abdominal wall 8 months postprostatectomy. BCCP is an aggressive type of prostate cancer, which might be challenging to diagnose based on routine protocols. This results in delayed diagnosis and treatment and thus poor prognosis. Furthermore, patients with this subtype of prostate cancer need appropriately designed, and maybe a totally different follow-up regimen as PSA is of no use for BCCP patients. Finally, diagnosis of BCCIS, if agreed upon its existence needs to be studied in larger cohorts as a precursor lesion.

Genomic Amplification

AbstractAs a rare subtype of prostate carcinoma, basal cell carcinoma (BCC) has not been studied extensively and thus lacks systematic molecular characterization. Here we applied single-cell genomic amplification and RNA-Seq to a specimen of human prostate BCC (CK34βE12+/P63+/PAP−/PSA−). The mutational landscape was obtained via whole exome sequencing of the amplification mixture of 49 single cells, and the 5 putative driver genes mutated are CASC5, NUTM1, PTPRC, KMT2C and TBX3. The top 3 nucleotide substitutions are C>T, T>C and C>A, similar to common prostate cancer. The distribution of the variant allele frequency values indicated these single cells are from the same tumor clone. The transcriptomes of 69 single cells were obtained, and they were clustered into tumor, stromal and immune cells based on their global transcriptomic profiles. The tumor cells specifically express basal cell markers like KRT5, KRT14 and KRT23, and epithelial markers EPCAM, CDH1 and CD24. The transcription factor (TF) co-variance network analysis showed that the BCC tumor cells have distinct regulatory networks. By comparison with current prostate cancer datasets, we found that some of the bulk samples exhibit basal-cell signatures. Interestingly, at single-cell resolution the gene expression patterns of prostate BCC tumor cells show uniqueness compared with that of common prostate cancer-derived circulating tumor cells. This study, for the first time, discloses the comprehensive mutational and transcriptomic landscapes of prostate BCC, which lays a foundation for the understanding of its tumorigenesis mechanism and provides new insights into prostate cancers in general.

Sebaceous gland tumors and other tumors exhibiting sebaceous differentiation have been described in humans (1,2,3). Tumors of the sebaceous gland can be induced in rats and mice following topical application of carcinogens (4), but spontaneous mixed tumors of basal cell origin rarely occur in mice.
