Lately, I’ve been told that I hardly keep up to my words. This particular trait of mine has never failed me my entire life but of late, it’s been plaguing me in ways I can’t imagine. As promised, I would like to post up a medically related article for every other post in this blog. To kick-off my case studies , lets look into : Mucous Retention Cyst.

Introduction : A mucous cyst is a benign, common, mucus-containing cystic lesion of the minor salivary glands in the oral cavity. Some authors prefer the term mucocele since most of these lesions are not true cysts in the absence of an epithelial lining. The lesions can be located :
1. Directly under the mucosa (superficial mucous cyst),
2. In the upper submucosa (classic mucous cyst),
3. or in the lower corium (deep mucous cyst).
Two types of mucous cysts occur based on the histologic features of the cyst wall:
- a mucous extravasation cyst formed by mucous pools surrounded by granulation tissue (92%),
- a mucous retention cyst with an epithelial lining (8%).
PathPhysiology
The mechanism of mucous cyst formation is unclear; however, a traumatic etiology rather than an obstructive phenomenon is considered more likely. The frequent location of the mucous cyst in the lateral aspect of the lower lip also supports the role of trauma as an etiologic factor. Although obstruction may play a role in the etiology of the mucous cyst, Lymphatic vessels may also contribute to the early stages of mucous cyst development. Specifically, the growing mucous cyst may induce a pressure gradient that causes lymphatics to swell with interstitial fluid, eventually rupturing and delivering this fluid back to the mucous cyst.
Mucous cyst is a benign condition and non-fatal. Frequent in young males.
Case Study #1/2010
(new reference #no. system to start logging my cases, damn the punters !)
Male, 28yrs. Presents with a palpable growth , painless, on left lower lip inside. Probably the size of a BB pellet(<5mm). No visible lesion or ulceration on growth. The surface of epithelia is rather smooth, shiny and dome shaped.
Patient complained of an ulcer located in the same area which didn’t heal after 2 months. Ulcer was continuous for the course of 2 months, unchanged diet and lack ulcer management did not help either. Bonjela damn it !
After initial observation, we can conclude that growth is benign and related to salivary ducts. Differentials would be lichen planus, Stomatitis, neoplasm, hemangioma and lipomas.
After consults with dermatologists and surgeons, we conclude that a conservative treatment method should be used to the painless nature of the cyst. Fortunately the cyst is not lying on a nerve ending or irritating pain fibres. With time, the cyst may dissolve itself or daily salt water gargle should help speed up the process. In the event the cyst grows or the pain factor has kicked in, we should look into surgical excision. This, I would gladly do with a scalpel, vodka(or whiskey) and loads of sterile gauze.
Surgical Care
For definitive management,
- The treatment of choice for a deep mucous cyst and the classic form is surgical excision, which should include the immediate adjacent glandular tissue.
- Cryosurgery with liquid nitrogen spray or cryoprobe is an alternative therapeutic modality. After day 4 to week 1, a necrotic surface is observed in the treated area.
- The latter separates from the surrounding mucosa in 1-2 weeks, exposing a new epithelialized surface. The advantages of the procedure include a simple application, minor discomfort during the procedure, and a low incidence of complications (eg, secondary infection, hemorrhage); however, the possibility of recurrence exists.
The patient has no further complaints. It didn’t occur to him that a lump in his mouth wasn’t abnormal, what more could I ask of him. In fact that useless bum doesn’t even want to get it checked when referred to the 2nd coolest doctor around, Dr.M. (sadly, he happens to be the father of our dearest Anuisafag, I sympathize him at times.)
With references to a couple of online medical sites and journals, I was able to conjure up the above. I seriously got to broaden my horizons after this because not everything in this field is always related to the heart, lungs, kidney or brain. Russian Doctors truly have it easy, having every Tatyana, Dmitri and Elena come in with either a heart problem, pulmo-infection, stroke, hepato-renal failure or even some cheap STD.
