Ovarian remnant syndrome is a condition that occurs when ovarian tissue is left behind following oophorectomy, causing development of a pelvic mass, pelvic pain, and occasionally dyspareunia. Ovarian remnant syndrome (ORS) is characterized by the presence of residual ovarian tissue after a woman has had surgery to remove one ovary or both ovaries (oophorectomy). Signs and symptoms
If ovarian hormones are present after the ovaries are removed can be a sign that ovarian tissue still remains. Signs and symptoms may include pelvic pain, a pelvic mass, or the absence of menopause after oophorectomy. Factors may include pelvic adhesions (limiting ability to see the ovary or causing it to adhere to other tissues); anatomic variations; bleeding during surgery; or poor surgical technique. Treatment is indicated for people with symptoms and typically involves surgery to remove the residual tissue. Therapy for those who refuse surgery, cannot have surgery, or do not have a pelvic mass may include hormonal therapy to suppress ovarian function.Some women have symptoms consistent with endometriosis, including difficult or painful intercourse; urinary symptoms; or bowel symptoms. It is likely that some women with ORS dont have any symptoms, but the rate of this is unknown. In most cases, symptoms occur within the first five years of the oophorectomy, although there are reports of ORS presenting 20 years after the initial surgery. Cause
The cause of ORS is the unintentional retention of ovarian tissue after the procedure to remove the ovaries. If a woman is receiving hormone replacement therapy, distinguishing from other disease process may be difficult.
Freckles are clusters of concentrated melaninized cells which are most easily visible on people with a fair complexion. Freckles do not have an increased number of the melanin-producing cells, or melanocytes, but instead have melanocytes that overproduce melanin granules (melanosomes) changing the coloration of the outer skin cells (keratinocytes). As such, freckles are different from lentigines and moles, which are caused by accumulation of melanocytes in a small area. Freckles can appear on all types of skin tones. Of the six Fitzpatrick skin types, they are most common on skin tones 1 and 2, which usually belong to North Europeans. However, it can also be found on people all over the world. Biology
The formation of freckles is caused by exposure to sunlight. The exposure to UV-B radiation activates melanocytes to increase melanin production, which can cause freckles to become darker and more visible. This means that one who has never developed freckles may develop them suddenly following extended exposure to sunlight. Freckles are predominantly found on the face, although they may appear on any skin exposed to the sun, such as arms or shoulders. Heavily distributed concentrations of melanin may cause freckles to multiply and cover an entire area of skin, such as the face. Freckles are rare on infants, and more commonly found on children before puberty. Upon exposure to the sun, freckles will reappear if they have been altered with creams or lasers and not protected from the sun, but do fade with age in some cases.
