Mutations in the PTEN gene are known to cause PTEN Hamartoma Tumor Syndrome (PHTS), an autosomal dominant disorder. This syndrome is characterized by proliferative lesions in various tissues, including the thyroid gland, breast, gastrointestinal system, kidneys, and endometrium.

In male patients, large cell calcifying Sertoli cell tumors associated with prepubertal gynecomastia can be observed. We present a case of prepubertal gynecomastia that led to a diagnosis of PJS durin...
