Mucinous cystadenoma of the appendix – case report

Abstract

Tumors of the appendix are extremely rare and constitute about 0.4% of all tumors of the gastrointestinal tract. The most common benign neoplasm is mucinous cystadenoma, which can be found in 0.6% of all excised appendices and it rarely produces any symptoms. We present the case of a female patient who underwent surgery in the Department of Surgery due to suspicion of an appendicular abscess. On the postoperative pathology study, the diagnosis of a tumor of the appendix (mucinous cystadenoma) was made. Mucinous cystadenoma is rarely included in the differential diagnosis of a non-specific abdominal pain accompanied by non-characteristic laboratory test results and imaging studies. There are no unequivocal guidelines and algorithms of managing this disease. Long-term prognosis is good in the case of a benign tumor.

Strong Magnetic Field Annealing for Improved Phthalocyanine Organic Thin‐Film Transistors

“…Thermally annealed films were heated in air at 225 °C for 30 min then left to cool to room temperature before data collection. The azimuthally‐integrated GIWAXS patterns of H 2 Pc and CuPc ( Figure ; Figure S1, Supporting Information) are in good agreement with the predicated α phase single crystal diffraction patterns found in literature (H 2 Pc CCDC# 118 412, [ 31 ] CuPc CCDC# 219 250 [ 32 ] ). While the predicated single crystal diffraction pattern of α‐phase ZnPc could not be found from literature, room temperature physical vapor deposition generally result in the formation of the metastable α‐phase polymorph that exhibits small spherical crystallites.…”

An inverted appendix found on routine colonoscopy: A case report with discussion of imaging findings

“…In addition, mucinous cystadenoma of the appendix represents a rare cecal lesion that may mimic AI. Indeed, in a 2017 case report, Janczak et al describe a 66-year-old woman who presented with symptoms and radiologic findings consistent with a periappendiceal abscess [16]. Laparotomy revealed a large amount of gelatinous material in the peritoneal cavity as well as a ruptured mucinous cyst of the appendix.…”

A green route to prepare metal-free phthalocyanine crystals with controllable structures by a simple solvothermal method

“…36-1882), and its detailed unit cell parameters are as follows. Space group: C 2 /n (15), cell: 33,35,36 Herein, the two predominant crystal planes for b-phthalocyanine (Fig. 4a) can be indexed as (001) and (201(_)), which correspond to 2q ¼ 7.1 and 9.1 , respectively.…”
