abstract = {Cribriform tumor is a distinctive cutaneous adnexal tumor
with a cribriform growth pattern. Initially described as
carcinomas, cribriform tumors exhibit an indolent clinical
course. In contrast to many other adnexal skin neoplasms,
the oncogenic driver of cribriform tumors is still unknown.
This study aims to provide a novel characterization of
cribriform tumors, focusing on the molecular and gene
expression profiles revealed by whole transcriptome analysis
using RNA sequencing and DNA methylation analysis, and
describe the resulting novel genetic and protein biomarkers.
The study analyzed 15 cases of cribriform tumors, including
five female patients. The median age at diagnosis was 62
years (range: 37-86 years). The most common tumor locations
were lower (n = 10) and upper extremities (n = 5).
Histopathological analysis revealed that all tumors were
dermally located, with subcutaneous extension in 11 cases.
All cases exhibited a combination of trabecular, cystic, and
cribriform growth patterns. Unsupervised clustering based on
DNA methylation and transcriptomic profiles confirmed
cribriform tumors as a strikingly homogeneous molecular
entity, molecularly distinct from other adnexal neoplasms.
The low-risk G2/M and CINSARC transcriptomic signatures
detected in all tested cases further supported the indolent
nature of this neoplasm. Copy number variation analysis
derived from DNA methylation analysis revealed recurrent
6q/9q codeletion in 7/8 tested cases. This codeletion was
confirmed by FISH targeting the 6q and 9q loci in 6 cases
tested. RNA sequencing data did not reveal any recurrent
specific fusions or specific pathogenic variants. Gene
expression analysis focusing on differentially expressed
genes between cribriform tumors and other cutaneous tumors
revealed overexpression of CD38 in all cribriform tumors.
Consistent with these findings, immunohistochemical analysis
demonstrated CD38 expression in all cribriform tumors but
not in controls (n=29). In conclusion, our findings support
that cribriform tumors represent a homogeneous group of
cutaneous adnexal neoplasms characterized by recurrent 6q/9q
co-deletions and CD38 expression.},
