Pediatric thyroid-like follicular renal cell carcinoma-a post-neuroblastoma case with comprehensive genomic profiling data.

Thyroid-like follicular renal cell carcinoma (TLFRCC), an emerging subtype of renal cell carcinoma, presents diagnostic challenges due to its resemblance to normal thyroid tissue. Here, we report a rare case of TLFRCC in a pediatric patient, a demographic rarely affected by this subtype. Histologically resembling a typical TLFRCC, our case exhibited unique features including post-neuroblastoma development, occurrence in a male teenager, and diffuse MelanA expression, which has not been previously reported in TLFRCC.

[The pioneering case of ovarian cryopreservation in childhood in Hungary].

With the development of the paediatric oncohaematological care and improving healing results, the focus on survival with high quality of life increases. Some oncohaematological treatments have a high gonadotoxicity and can cause infertility, therefore the fertility preservation is gaining ground worldwide. Most of the fertility preservation procedures are not yet available in childhood in Hungary.

[Incomplete androgen insensitivity].

In the androgen insensitivity syndrome (AIS) the androgen effect is decreased in the fetus and the youth despite the adequate testosterone production. Usually the mutation of the androgen receptor is responsible for the disease. In the presented case the external genitalia were similar to female genitalia but masses were palpable in the labioscrotal fold.
