  • Zeis
  • Specifically, a high index of suspicion is warranted in patients who present with recurrent or treatment-resistant chalazion (obstruction and inflammation of the Meibomian or Zeis glands that commonly presents as a nontender nodule on the inner eyelid), blepharoconjunctivitis (inflammation of both conjunctiva and eyelids that present with erythema, edema and crusting of the eyelid margins with pink conjunctiva) or keratoconjunctivitis (inflammation of the cornea and conjunctiva with associated epithelial keratitis).

  • hyperplasias
  • These look just the same as sebaceous hyperplasias to the naked eye but tend to occur in larger breeds and usually on the eyelids or head. (marvistavet.com)
  • They commonly appear as papillated (nipple like projections) masses sometimes 1 cm in diameter while sebaceous hyperplasias have a shiny, keratotic (horny growth especially like that of a wart) surface. (wearethecure.org)
  • sebocytes
  • Detailed gland structure, plus the active migration of individual sebocytes and cohorts of sebocytes were measured. (harvard.edu)
  • Expression of IL-1a and b was demonstrated in sebaceous glands by immunohis-tochemistry (162), and mRNA for IL-1a was detected in cultured sebocytes (163). (americorpshealth.biz)
  • cells
  • These cells are constantly replaced by new growth at the base of the glands. (infoplease.com)
  • They produce porphyrins which are probably partially dispersed into the surrounding medium composed of sebaceous lipids and desquamating cells from the follicular wall . (springer.com)
  • The current belief is that the epidermal sebaceous gland (SG) is maintained by unipotent stem cells that are replenished by multipotent stem cells in the hair follicle (HF) bulge. (nih.gov)
  • Oil-red-O and Sudan black stains can be used to highlight sebaceous cells. (clinicalpainadvisor.com)
  • disorders
  • This study demonstrates that CARS microscopy is a promising tool for studying the sebaceous gland and its associated disorders in three-dimensions in vivo. (harvard.edu)
  • surface
  • These lumps must be differentiated from infections due to herpes or other STDs, penile warts, angiokeratomas, scabies , folliculitis , Tyson glands (modified sebaceous glands around the corona and inner surface of the prepuce of the penis). (healthtap.com)
  • Between the gland and the surface is up to 3 mm of tissue that can absorb light and be damaged. (americorpshealth.biz)
