Clinical features of sarcoidosis patients presenting with head and neck manifestations - a two-center retrospective study and proposal of a diagnostic algorithm for the otorhinolaryngologist

When inflammation is not just inflammation-A review of systemic diseases of the nose and sinuses part 1: IgG4-related disease and sarcoidosis

BACKGROUND

Chronic rhinosinusitis is a very common condition. IgG4-related disease (IgG4-RD) and sarcoidosis are systemic diseases which can contribute to the development of chronic rhinosinusitis in select patients.

OBJECTIVE

Characterize the presenting features, diagnostic criteria, workup, and management of sinonasal IgG4-RD and sarcoidosis as they are encountered in otolaryngology clinics.

METHODS

Full length manuscripts published 2000 or later were reviewed. A separate search was conducted for each disease. Pertinent clinical features related to sinonasal manifestations of IgG4-RD and sarcoidosis were collected and reported in this review.

RESULTS

404 references were discovered during literature review process. In total, 42 references for IgG4-RD and 34 references for sarcoidosis were included in this review.

CONCLUSION

IgG4-RD and sarcoidosis are autoimmune inflammatory conditions that can affect many systems of the body. For both disease entities, sinonasal disease is a less common presentation which can lead to delayed diagnosis. Sinonasal IgG4-RD commonly presents in the setting of multisystem disease. All with other clinical features, biopsy plays a key role in the diagnosis for both diseases. Treatment for IgG4-RD consists primarily of steroids and rituximab which can lead to excellent and durable remission. A variety of immunosuppressive agents are used in the management of sarcoidosis. Surgery for IgG4-RD is primarily utilized for tissue biopsy, although resection or debulking may be considered. For sarcoidosis, surgery can be used for tissue biopsy and functional sinus surgery can offer symptomatic relief in many patients.

[Sarcoidosis in head and neck area - a diagnostic challenge using the example of skin manifestations]

BACKGROUND

 Sarcoidosis is a granulomatous multisystem disease of unknown etiology and relatively rare. The heterogeneous clinical picture is a diagnostic challenge. We are investigating whether the superficially visible cutaneous lesions can lead to the differential diagnosis of sarcoidosis and what systemic manifestations are present.

MATERIAL AND METHODS

 As part of our exploratory retrospective investigation (eight years) a total of 32 patients with cutaneous sarcoidosis were identified and analyzed.

RESULTS AND CONCLUSION

 In many cases the dermatologists considered the differential diagnosis of sarcoidosis even before biopsy (71.8%); in our previous study with ENT-patients the diagnosis wasn´t considered in a single case by the attending doctors at this time and without any prevoius suspicion. Sarcoidosis of the skin in the head and neck area is the second most common cutaneous manifestation. After biopsy (Gold standard) the search for further possible organ manifestations is essential (e.g. lungs, heart) to treat them in an early stage and to prevent complications of a possible chronic course (including cardiac arrhythmias, pulmonary fibrosis).
