Diagnosing bullous myringitis involves using an otoscope to spot distinctive white sack-like structures on the eardrum.Ear pain is the primary complaint. However, differentiating it from acute otitis media can be difficult, leading to early misdiagnosis.The rarity of bullous myringitis, especially compared to acute otitis media, can result in common misdiagnoses.
Viral otitis may result in blisters on the external side of the tympanic membrane, which is called bullous myringitis (myringa being Latin for "eardrum"). [24] However, sometimes even examination of the eardrum may not be able to confirm the diagnosis, especially if the canal is small.
Bullous myringitis leads to the development of bullae on the tympanic membrane that can be punctured to give pain relief. [35] Foreign body in the ear canal can cause pain and be treated with careful removal. [8] Infected sebaceous cyst is treated with incision and drainage of the cysts, oral antibiotics and otorhinolaryngology assessment. [8]
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes H65-H75 within Chapter VIII: Diseases of the ear and mastoid process should be included in this category.
Angina bullosa haemorrhagica is a condition of the mucous membranes characterized by the sudden appearance of one or more blood blisters within the oral cavity. [1]: 808 The lesions, which may be caused by mild trauma to the mouth tissues such as hot foods, typically rupture quickly and heal without scarring or further discomfort. [2]
The term "erythema multiforme majus" is sometimes used to imply a bullous (blistering) presentation. [2] According to some sources, there are two conditions included on a spectrum of this same disease process: Stevens–Johnson syndrome (SJS) Toxic epidermal necrolysis (TEN) which described by Alan Lyell and previously called Lyell syndrome[5].
Granular myringitis is a long term condition in which there is inflammation of the tympanic membrane in the ear and formation of granulation tissue within the tympanic membrane. [1] It is a type of otitis externa. [2] Without treatment it can lead to narrowing of the ear canal. [1]
Erythema multiforme (EM) is a skin condition that appears with red patches evolving into target lesions, typically on both hands. [2] [3]It is a type of erythema possibly mediated by deposition of immune complexes (mostly IgM-bound complexes) in the superficial microvasculature of the skin and oral mucous membrane that usually follows an infection or drug exposure.
