  • Intraabdominal cystic lymphangioma is an uncommon lesion. It is usually found incidentally in patients presenting with an acute abdomen. Laparoscopic excision of intraabdominal cystic lymphangioma is an easy and safe procedure in children. We report one case of cystic lymphangioma in a 6.year-old female. The lesion was located on the left side of the transverse mesocolon. Laparocopic excision of the cyst was performed without complications.

  • Adrenal cystic lymphangiomas are extremely rare entities that are often identified incidentally, with less than 60 cases reported to date. We found a protruding ovoid mass consisting of a multiloculated cystic lesion within right adrenal gland in the cadaver of a 75-year-old Korean man. The epithelial cells lining the adrenal cyst were diffusely positive for cluster of differentiation 31 and podoplanin, and negative for pan-cytokeratin. The histopathological diagnosis confirmed a cystic lymphangioma arising from the adrenal gland. Post-mortem findings of the present case are discussed based on the clinicopathological features of adrenal cystic lymphangiomas.

  • Antisense oligonucleotide (ASO) technology has become an attractive therapeutic modality for various diseases, including Mendelian disorders. ASOs can modulate the expression of a target gene by promoting mRNA degradation or changing pre-mRNA splicing, nonsense-mediated mRNA decay, or translation. Advances in medicinal chemistry and a deeper understanding of post-transcriptional mechanisms have led to the approval of several ASO drugs for diseases that had long lacked therapeutic options. For instance, an ASO drug called nusinersen became the first approved drug for spinal muscular atrophy, improving survival and the overall disease course. Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene cause cystic fibrosis (CF). Although Trikafta and other CFTR-modulation therapies benefit most CF patients, there is a significant unmet therapeutic need for a subset of CF patients. In this review, we introduce ASO therapies and their mechanisms of action, describe the opportunities and challenges for ASO therapeutics for CF, and discuss the current state and prospects of ASO therapies for CF.

  • Adenoid cystic carcinoma of the uterine cervix is a rare tumor accounting for less than 1% of all cervical adenocarcinoma. This tumor is characterized by aggressive biological behavior with frequent local recurrence or metastatic spread, postmenopausal onset, and occasional association with conventional squamous cell carcinoma. The cytologic diagnosis of adenoid cystic carcinoma in the uterine cervix is often difficult because of negative smear due to intact overlying mucosa, cytologic findings mimicking endometrial cells, and masquerade as squamous ceil carcinoma. Recently we have experienced a case of adenoid cystic carcinoma arising in the uterine cervix, which was identified on the routine Papanicolaou smear and was histologically confirmed by the consequent biopsy. The smear showed abundant cellularity composed of relatively uniform cells. The tumor cells were arranged in small clusters, acini, naked cells, and loose sheets with abortive cribriform pattern. There were scattered globoid basement membrane-like materials and tumor diathesis. The nuclei were pleomorphic and showed hyperchromatic and coarsely granular choromatin with inconspicuous nucleoli. The punch biopsy of the uterine cervix showed typical histologic findings of adenoid cystic carcinoma characterized by tumor nests composed of hyperchromatic uniform basaloid cells, cribriform pattern, and cylindrical hyaline bodies.

  • A cystic compound odontoma in the maxillary sinus occurred in a 13-year-old boy. who had missing right upper third molar without having the history of extraction of the wisdom tooth. He complained nasal stuffiness. headache. and pain on the affected face. resembling any sign and symptoms of the maxillary sinus problems. The cystic compound. sized 2 x 1.5 cm in diameter was pedunculated and attached on the posterior wall of the right maxillary sinus and above the antral floor. The location of the compound odontoma in the maxillary sinus was confirmed after panoramic. waters. spiral tomographic. CT examinations and surgical exploration. Its location was on the medial. posterior. superior to the normal position of the maxillary third molar or the maxillary dental arch. The cystic odontoma in the maxillary sinus made the patient have the signs and symptoms of maxillary sinusitis. The cystic compound odontoma might be originated from the dental lamina of the missing upper right third molar. The 'V principle' of the upper jaw growth and the pneumatization process of the maxillary sinus could explain why the compound odontoma had peduncular shape and the location of odontoma was on the medial. superior to the normal position of the maxillary dental arch.

  • To present a rare case of a cystic giant schwannoma of the sacrum mimicking aneurysmal bone cyst (ABC). A 54-year-old man visited our institute complaining left leg weakness and sensory change for several years. Magnetic resonance imaging revealed a large multilocular cystic mass with canal invasion and bone erosion confined to left S1 body. The lesion showed multiple septal enhancement without definite solid component. Initially the tumor was considered as ABC. The patient underwent grossly-total tumor resection with lumbosacral reconstruction via posterior approach. The tumor was proved to be a cystic schwannoma. The postoperative course was uneventful and the patient was relieved from preoperative symptoms. We present a rare case of pure cystic giant schwannoma confined to sacrum mimicking ABC. The surgical treatment is challenging due to the complex anatomy of the sacrum. Schwannoma should be considered in the differential diagnosis of osteolytic sacral cysts.

  • To establish the differential diagnosis and treatment method in bovine ovarian cysts, specially ovarian cysts with corpus luteum, serum progesterone concentration and ulrasonography for measuring the cyclic area, thickness of cystic wall and echogenicity of corpus luteum were investigated in cystic ovaries from slaughtered cows. The incidence rates of ovarian cysts were follicular cyst 69.2% and luteal cyst 30.8%. The incidence rates of 8 various types of ovarian cysts were as follows; 2Ba 32.3%, 2Aa 25.8% and 2Bb 14.5%, respectively. The thickness of cystic wall were 2Bb 3.93mm, 2Ab 3.70mm and 1Aa 1.93mm and the serum progesterone concentrations were above 1.0ng/$m\ell$ in 2Ab, 2Bb and IAa, respectively. The cystic area of ovarian cysts with corpus luteum was 288.30mm2, but ovarian cysts without corpus luteum 542.30$\textrm{mm}^2$, and the thickness of cystic wall 2.12mm and 2.40mm, respectively. The serum progesterone concentration was 1.91ng/$m\ell$ in ovarian cysts with corpus luteum and 1.20ng/$m\ell$ ovarian cysts without corpus luteum. There was not the correlations between thickness of cystic wall and serum progesterone concentration in ovarian cysts with corpus luteum, whereas, was the correlations in ovarian cysts without corpus. These results indicated that PGF2$\alpha$ analogues can be choice for treating the ovarian cysts with corpus luteum because serum progesterone concentrations were above 1.0ng/$m\ell$ in ovarian cysts with corpus luteum. In conclusion, it is suggest that ultrasonography is useful diagnostic tool for diagnosing and choicing of treatment remedy in cystic ovaries of bovine.

  • Purpose: Adenoid cystic carcinoma is a rare type of eccrine sweat gland carcinoma. Although it is mostly known as a neoplasm of the salivary gland, it could occur as a primary skin tumor. We present a patient with a primary cutaneous adenoid cystic carcinoma at the genital area. Methods: A 60-year-old man had a slowly growing 1 cm sized single tender mass near the left scrotum and he underwent excisional biopsy at a local clinic. A diagnosis of adenoid cystic carcinoma was made and thus he was transferred to our hospital. In physical examination, other specific findings were not detected except a linear scar caused by a previous skin biopsy near the left scrotum. In CT scan, PET-CT scan and endoscopy, there was no evidence of neoplasm in other organs. It was diagnosed as the primary cutaneous adenoid cystic carcinoma and then wide excisions were performed including total 4.5 cm margin of normal skin. Results: Microscopic findings revealed proliferation of tumor cell islands with cribriform or tubular patterns containing several round, pseudocystic structures. The tumor cells showed basaloid cells with uniform and small nuclei. Tumor cells infiltrated into the dermis and upper portion of subcutaneous tissue. There was multifocal perineural invasion of tumor cells. In postoperative 6 months, we found no recurrence and other complications. Conclusion: Herein we found a rare case of primary cutaneous adenoid cystic carcinoma at the genital area.
