Dumbbell-Shaped Neurofibroma Over the External Ear.

Shirol SS, Kodaganur S, Dani AA, Bhagwat PV - J Cutan Aesthet Surg (2015 Jul-Sep)

Bottom Line: Dumbbell-shaped swellings in neurofibroma have been commonly described in the spine, thorax, cranial cavity, and pelvis; however, dumbbell-shaped swellings in the peripheries are rare.Here, we report a dumbbell-shaped neurofibroma over the pinna in an 18-year-old female patient, its successful surgical management, and its association with Hashimoto thyroiditis.To the best of our knowledge, this is the first ever case to be reported of a dumbbell-shaped neurofibroma over the external ear and only the fourth case of neurofibromatosis type 1 (NF1) to be associated with Hashimoto thyroiditis.

Figure 4: (a) Histopathology of neurofibroma (b) Histopathology of Hashimoto thyroiditis

Mentions: A female patient aged 18 years presented with a swelling over the left ear of 1-year duration associated with decreased hearing. Clinical examination revealed a soft swelling measuring about 2 cm × 2 cm obliterating the concha of the left ear and the external auditory canal [Figure 2a]. Similarly, there was another soft swelling of 3 cm × 2 cm in the retroauricular region completely obliterating the retroauricular groove [Figure 2b]. There were multiple cafe au lait macules of varying sizes over the body. There was also a diffuse thyroid swelling involving both the lobes with no apparent nodularity. On subjecting the patient to slit-lamp examination, there were multiple Lisch nodules over both the irises. Tuning fork tests revealed mild conductive hearing loss in the left ear. Fine-needle aspiration cytology (FNAC) of the thyroid swelling showed features suggestive of Hashimoto thyroiditis [Figure 4b].
