Lipoid proteinosis; a rare pathology, requiring multidisciplinary input

A male patient in his early childhood presented to rheumatology with a hoarse voice and recurrent oral and cutaneous ulceration. Serological investigation revealed persistently elevated inflammatory markers. Despite compliance to treatment, flare-ups persisted, prompting the use of further treatment. An airway endoscopy revealed cystic changes to the left vocal cord. Referral to ophthalmology revealed multiple, waxy, skin-coloured, beaded papules on thickened, irregular eyelid margins with distichiasis, in keeping with moniliform blepharosis. Enrolment into the 100 000-genome project helped clinch the diagnosis of lipoid proteinosis. Although this case highlights the diagnostic power of genetics, it also sheds light on the importance of targeted clinical referral. When one considers the typical symptoms and signs of lipoid proteinosis, referral to a centre of rare diseases would have proven effective in not only avoiding polypharmacy but also reducing the psychological burden of several years of uncertainty must have had on our patient.
