Pediatric-type follicular lymphoma is an uncommon and newly recognized entity of lymphoid neoplasm commonly encountered in the young population. Despite its indolent clinical course and localized nodal involvement, it has been characterized by its high-grade histopathological features. The overlapping features between this disease and several entities have made approaching this unique entity significantly challenging, with all such features being reflected in the strict diagnostic criteria highlighted by the WHO 2016 lymphoid malignancy classification. Despite its characteristic high-grade histology, its cure rates have remained high, with relapse and transformation rarely occurring. Interestingly, several cases have achieved remission following nodal disease resection, possibly eliminating the need for chemotherapy and radiation and preventing long-term morbidities from later approaches in disease survivors.

Testicular follicular lymphoma (TFL) is an exceedingly rare lymphoma that typically occurs in young male patients and is now recognized as a distinct diagnostic entity in the International Consensus Classification. TFL shows some clinicopathologic and genetic overlap with pediatric-type follicular lymphoma (PTFL). We report a case of TFL occurring in an otherwise healthy 4-year-old boy who presented with painless scrotal swelling.

Pediatric-type follicular lymphoma (PTFL) is an extremely rare B-cell lymphoma that primarily affects children and young adults, typically in individuals under 25 years old, with a median age of 15 years. Here, we report a rare case of PTFL in a 27-year-old adult male who presented with a slow-growing mass near his left ear. Initial CT scans of the neck revealed two oval-shaped, smooth, well-defined, homogeneously enhancing soft tissue density lesions in the superficial lobe of the left parotid gland.

Only 10% of new lymphoma diagnoses in the USA occur in children < 15 years. Although the same diagnostic criteria apply to both adult and pediatric lymphomas, there are important differences in some lymphoma subtypes. These differences are recognized by the World Health Organization (WHO) with the recent 2022 classification of pediatric tumors including pediatric hematopoietic tumors.

The authors present two cases of conjunctival pediatric-type follicular lymphoma. A 14-year-old Black boy and 14-year-old Black girl were each referred for evaluation of a painless salmon-colored conjunctival lesion. Both patients underwent excisional biopsy.
