Background Inflamed epidermal cysts are common clinical conditions, and they frequently form abscesses. We designed a study to delineate the bacteriology of inflamed epidermal cysts. Methods We enrolled 61 adult patients with inflamed epidermal cysts characterized by surface erythema, with or without tenderness, or localized abscess formation within the cyst cavity. Incision and drainage of the...

Abstract: The odontogenic keratocyst be a developmental cyst that's important due to its specific clinical behavior and histopathology. They arise from remnants of the epithelial structures that are related event teeth occur predominantly intraosseous. However, they occasionally can appear extraosseous in gingiva as peripheral counterparts. is most common location keratocyst, but other sites li...

BACKGROUND An epidermoid cyst is a common epithelial-lined cyst. There have been many studies on epidermoid cysts, but few focused on ruptured epidermoid cyst and its histopathologic characteristics. OBJECTIVE We evaluated the histopathologic differences between ruptured and unruptured epidermoid cysts, and their relationships. METHODS We retrospectively examined 359 excision biopsy specime...

Epidermal inclusion cysts are benign cutaneous lesions caused by dermal or subdermal implantation and proliferation of epidermal squamous epithelium as a result of trauma or surgery. They are typically located on the scalp, face, trunk, neck, or back; however they can be found anywhere on the body. Lesions are asymptomatic unless complicated by rupture, malignant transformation to squamous cell...

Tissue replenishment from stem cells follows a precise cascade of events, during which stem cell daughters first proliferate by mitotic transit amplifying divisions and then enter terminal differentiation. Here we address how stem cell daughters are guided through the early steps of development. In Drosophila testes, somatic cyst cells enclose the proliferating and differentiating germline cell...
