The objective of this study is to evaluate the clinicopathologic features of pigmented eyelid cysts. A case-control study was conducted, examining consecutive pigmented and nonpigmented eyelid hidrocystoma excision specimens. Over a 4-year period, 9 pigmented eyelid hidrocystomas were identified, representing 13% (9/70) of all hidrocystoma excisions. Compared to controls (n = 14), no difference existed for age [mean age 59 (44-78 years) vs. 60 (42-82 years)] or size [mean diameter 2.3 (1-4 mm) vs. 2.7 (1-5 mm)] (pigmented
vs. nonpigmented, respectively), but a trend for female, left side, and lower lid predominance for pigmented hidrocystomas existed: 8:1 versus 7:7 F:M; 7:2 versus 7:7 left:right; 8:1 versus 9:5 lower:upper eyelid (pigmented vs. nonpigmented, respectively). Saracatinib mouse Clinically, the pigmented cysts’ color varied from dark blue, brown, and to black, and on gross examination, JQ-EZ-05 they expressed dark brown to black granular liquid contents. Applying histologic criteria of Jakobiec and Zakka, 8 of 9 and 14 of 14 pigmented and nonpigmented hidrocystomas were of apocrine type. Seven of 9 (78%) pigmented cysts and 6 of 14 (43%) nonpigmented hidrocystomas contained granular eosinophilic cyst contents and/or intracellular cytoplasmic
granular pigmented deposits by light microscopy. (The pigmented cyst contents did not survive processing in 2 cases.) By histochemistry (periodic acid Schiff with diastase, Sudan Black, and Fite acid-fast positive staining) and ultraviolet fluorescence, these sediments were determined to be lipofuscin pigments. No hidrocystomas had melanin Selleckchem Gilteritinib deposits, and one case had hemosiderin deposits in
a scarred cyst wall in addition to cyst lipofuscin pigments. In studies of chromhidrosis, both normal and chromhidrotic apocrine glands contain lipofuscin pigments; the sole difference lies in the amount of lipofuscin granules. Similarly, for eyelid apocrine hidrocystomas, lipofuscin pigments exist in both groups. Presumptively, the amount of lipofuscin and degree of its oxidation distinguish pigmented from nonpigmented apocrine hidrocystomas.”
“Purpose: It is advocated to delay the start of peritoneal dialysis (PD) at least 10-14 days after insertion of peritoneal catheter. The aim of this study was to investigate factors associated with catheter-related complications (CRC) in patients starting PD early (1-13 days) (ES) and late (14 days or more) (LS) after catheter implantation.
Material/Methods: Single center, retrospective analysis of CRC occurring within 14 days of follow up after peritoneal dialysis initiation in ES and LS group of patients.
Results: A total of 97 patients were analyzed. Seventy percent of them were ES. There were significantly more CRC in ES vs. LS (31% vs. 3%, p=0.01). Significantly more mechanical CRC occurred in ES than in LS (21% vs. 0%, p=0.01). Occurrence of infectious CRC did not differ between the groups.
