Warthin Tumor

Mucoepidermoid carcinoma (MEC) shows a wide morphologic spectrum, including epithelium with oncocytic or squamous metaplastic changes overlying a prominent cystic architecture, as well as tumor-associated lymphoid tissue. We illustrate a case of MEC of the parotid in a 17-year-old female, in which all these features occurred extensively, such that they accounted for almost the entire neoplasm, and closely mimicked Warthin tumor histologically. This highlights the need for diagnostic awareness of this particular morphologic variant of MEC, as patients could potentially be inappropriately discharged from follow-up if diagnosed with a benign neoplasm.

Abstract Introduction/Objective Warthin tumor-like mucoepidermoid carcinoma(WTL- MEC) is one of the subvariant of mucoepidermoid carcinoma. It mimics the histological features of metaplastic Warthin tumors (mWTs). To investigate the clinicopathological, molecular features, and bio-behaviors of WTL-MEC, we retrospected a cohort of 29 WTL- MEC patients. Methods/Case Report The clinicopathological and microscopic data were collected. Dual-color FISH analysis was performed on paraffin-embedded sections of 29 WTL- MEC patients and 16 mWTs patients using a MAML2 break- apart probe. Whole-exome sequencing and whole transcription sequencing were performed on 3 WTL-MEC and 3 typical mucoepidermoid carcinomas (TMEC) patients. Genetic data were bioinformatically analyzed by software MuTect (v1.7), PINDEL (v0.2.5), SnpEff (v3.0), and etc. Results (if a Case Study enter NA) The cohort of WTL-MEC included 10 male and 19 female patients with a median age of 42.3 years (range, 8 to 68 years). Microscopically, the WTL-MEC lesion consisted of multi-cysts with variant shapes and sizes. The cystic spaces were lined by bi-layered and multilayered oncocytic cells. A transition zone between the bi-layered oncocytic epithelium to the multilayered oncocytic epithelium was observed in WTL-MEC. The cords of epidermoid cells and mucous cells could be found. The germinal center, extensive hyalinization, and mucus extravasation were observed. MAML2 rearrangement was identified in 29 (100%) WTL-MEC. No rearrangement was observed in mWTs by FISH. MET was the most commonly mutated gene in TMEC, and PRDM11 was the most commonly mutated gene in WTL-MEC. Twenty-nine patients were alive without recurrent at the end of the follow-up periods(5–128M). One Patient died due to the metastasis to the lung. Conclusion compared with mWTs, WTL- MEC usually presented in the young, non-smoking female. The histological feature of WTL-MEC depended mainly on the transition zone of the bi-layered oncocytic epithelium and the multilayered oncocytic epithelium. And MAML2 status can confirm the diagnosis. CRTC1-MAML2 and PRDM11 mutations appear to be the main driver event of WTL-MEC. Prognosis was usually favorable, but recurrence or metastasis may rarely occur.

Abstract Background Hidradenoma papilliferum is a rare benign neoplasm arising from apocrine glands. It occurs commonly on the anogenital region of middle-aged women. It usually presents as a slow growing, solitary asymptomatic, skin colored or red nodule less than 1 cm in diameter. Case presentation The case is a 38-year-old, white woman who presented with a painful nodule occurring within a month in the himenal region of the posterior vaginal introitus. The nodule was excisied and the histology revealed a hidradenoma papilliferum. The diagnosis and treatment of hidradenoma papilliferum is possible with surgical removal and histopathological evaluation of nodules. Conclusion When an adult woman presents with a noduler lesion in the anogenital area, sexually transmitted diseases and other benign and malignant vulvar lesions, as well as malignant transformation is very rare but,should be kept in mind; however because it has been reported and long-term clinical follow-up is suggested

Abstract Low-grade B-cell lymphoma of mucosa-associated lymphoid tissue involving the kidney is rare. We report a series of 3 cases. The first case occurred in an 83-year-old woman who presented with back pain. The second case was a 53-year-old man with a history of sarcoidosis who was found, in the course of evaluation of sarcoidosis, to have a right renal mass. The third case occurred in a 72-year-old man who had a history of periorbital mucosa–associated lymphoid tissue lymphoma and had been treated with surgery and radiation 1 year prior to this presentation. Histologically, all 3 patients showed infiltrate of uniform small-to-medium–sized lymphocytes with irregular nuclear contours and abundant cytoplasm resembling centrocytes or monocytoid lymphoid cells. The first patient received chemotherapy without complications. The second patient underwent a partial nephrectomy and was asymptomatic at the subsequent follow-up. The third patient developed a pulmonary embolism following nephrectomy, and further follow-up is not available.

Pulmonary Malt Lymphoma

Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is indolent and progresses more slowly than other malignant lymphomas. The clinical features are not specific and the diagnosis can often be difficult. Here, we present two rare cases of pulmonary MALT lymphoma. Both patients were incidentally found lesions in the lungs with chest computed tomography during physical examination. They were finally diagnosed by pathological biopsy. One received complete resection, the other was treated with chemotherapy. There were no recurrence in the two patients during follow-up. We also review relevant literature to provide a better recognition of this disease.

AbstractBackground:Limited information is available on mucosa-associated lymphoid tissue lymphomas arising in the head and neck.Method:A retrospective analysis was conducted of 20 patients who were histologically diagnosed with mucosa-associated lymphoid tissue lymphoma and treated at our institution between January 1990 and December 2009.Results:Treatment consisted of surgical resection alone in two patients (10 per cent), surgical resection with consecutive radiotherapy in one (5 per cent), and radiotherapy alone in eight (40 per cent). Three patients (15 per cent) were treated with systemic chemotherapy, and three (15 per cent) received chemoradiotherapy. Three patients (15 per cent) were informed of the diagnosis but not treated for their condition.Conclusion:All of the 20 patients were still alive after a mean follow-up period of 50.8 months. Local treatment for mucosa-associated lymphoid tissue lymphoma of the head and neck should be the first choice in early-stage disease. However, prolonged follow up is important to determine these patients' long-term response to treatment.

Laser Excision

Inflammatory myofibroblastic tumor (IMT) is a benign neoplasm of intermediate biologic potential. It rarely occurs in the larynx, and it has not been previously reported in the epiglottis. We treated a 66-year-old woman who presented with progressive dysphonia and a mass on her suprahyoid epiglottis. The tumor was completely excised with a CO2 laser; no adjuvant therapy was administered. Histopathology revealed that the mass was an IMT. No evidence of recurrence was noted after 6 months of follow-up. We present what we believe is the first case of an epiglottic IMT to be reported in the literature, and we propose CO2 laser excision without adjuvant therapy as an acceptable treatment.
