Conjunctiva: Other Lesions/Tumours Flashcards
Describe Lymphoid Lesions?
- Occurs in young to middle-aged adults
- Range from benign reactive hyperplasia to lymphoma
o Similar clinical appearances - Light pink, salmon coloured lesion
- Relatively flat, smooth & soft
o Bulbar conjunctiva – oval
o Fornix conjunctiva – horizontal
Describe Kaposi Sarcoma?
- Slow growing malignant tumour associated w/ AIDS
- Can occur on skin or conj
- Rarer
- Painless or discomfort
- Vascular – red or purple
- Inferior fornix
- Tx:
o Investigation for HIV status – take in H&S
o Tx is for px as a whole not specifically for the lesion on the conj
o Radiotherapy
o Excision +/- cryotherapy
Describe a conjunctival haemorrhage?
– Will see much more regularly, conj is highly vascularised structure filled w/ lots of fragile vessels which can rupture & bleed & fill up the subconjunctival space
- Bruise but it’s not on the skin, it’s on the white of the eye, it will turn purple then yellow but like a bruise it will eventually go away
- Can occur w/ px just rubbing eye or anything that causes any strain w/ positive Valsalva e.g. straining, sneezing, coughing
- Usually painless, if anything there may be irritation – usually something the px sees in mirror or someone else sees in px’s eye first rather than something that they feel
- No treatment is necessary
Describe Molluscum Contagiosum?
- Most commonly seen in children but also seen in adults
- Oncogenic virus
- Characteristic lesions of skin & mucus membranes (often in eyelids & lashes – releases virus particles onto ocular surface that can cause recurrent conjunctivitis)
o Domes shaped, umbilicated shiney nodules - Associated follicular conjunctivitis
- Can be associated w/ HIV
- Excision of lesion to treat conjunctivitis
- Can give drops/lubricants/steroids to try & get rid of viral infection – but if only treating eye & not eyelid then will not go away completely
o Once excised – everything settles down
