[Hibernoma and cervical rib: two rare diseases, the same manifestation]
Abstract:
The hibernoma is a rare benign tumor of soft tissue, derived from remnants of fetal brown adipose tissue. A cervical rib is a supernumerary or accessory rib derived from the 7th cervical vertebra. CLINCAL CASE: 2-year-old girl, previously healthy, referenced to Pediatrics consultation, for left supraclavicular mass. No history of infectious diseases or systemic symptoms. At exam presented mass in supraclavicular left region, 1.5 to 2 cm in diameter, hard, mobile, non-adherent to the deep planes. Laboratory tests exclude an infectious or lymphoproliferative disease. In cervical radiograph we observed bilateral cervical ribs. Cervical ultrasound revealed calcified nodule 0.8 cm, compatible with calcified adenopathy. Biopsy was performed and histology revealed a hibernoma, which was completely removed surgically. This case illustrates the association of two diagnoses, uncommon in children. These were made during the investigation of lymphadenopathies, a frequent reason for pediatrics consultation.
