INTRODUCTION: The adenomatoid odontogenic tumor (AOT) associated with odontoma has been described as a new entity with overlapping features of adenomatoid-like structures and odontoma. Presentation of the case: We report the second case of AOT associated with odontoma in the posterior maxillary region. A 22-year-old patient presented expansion of the vestibular and palatine cortical wall of maxilla. Radiographic examination and computed tomography confirmed erosion of maxillary walls, root resorption, displacement of a neighboring tooth and radiopacities within the lesion...

Adenomatoid tumors (ATs) are rare, benign neoplasms occurring mainly in reproductive organs such as the uterus, ovaries, fallopian tubes, and testes. Uterine adenomatoid tumors (UATs) are generally incidentally diagnosed during histopathological examination of excisional biopsies performed for other indications, most commonly uterine leiomyomas. We herein present a 38-year-old woman who underwent laparoscopic excision of a uterine leiomyoma and a right ovarian teratoma. Microscopic examination of the excisional biopsy revealed that the enucleated uterine tumor was composed of proliferating glandular tissue covered with single-layered cells that were surrounded by proliferating smooth muscle cells, corresponding exactly to the features of UATs...

The new WHO 2016 classification of renal neoplasia encounters the new entity called "clear cell papillary renal cell carcinoma" (ccpRCC). The ccpRCC has been long included as a subtype of clear cell RCC histotype and it actually ranges from 2 to 9% in different routinely available cohort of renal carcinomas. Of important note, ccpRCC does not show any recurrences or metastases or lymph-node invasion and the outcome is always good. We reviewed twenty-four publications with available follow-up for patients (no...

Misdiagnosis of respiratory epithelial adenomatoid hamartomas for malignant tumors can lead to an aggressive surgical procedure, which is not necessary in the case of a respiratory epithelial adenomatoid hamartoma. Detailed analysis of sinonasal CT scans without contrast can help to distinguish respiratory epithelial adenomatoid hamartomas of the olfactory cleft from small malignant tumors (T1 and T2) of the olfactory clefts. Criteria in favor of diagnosis of small malignant tumors of the olfactory clefts on CT scans without contrast were unilaterality of masses in the olfactory clefts, large olfactory clefts /small olfactory clefts ratio ≥ 2 (sensibility at 91% and specificity at 100%), and presence of bone erosion...

BACKGROUND: Mutations previously considered drivers of malignant neoplasms also occur in benign tumors. From the biological perspective, the study of malignant and benign neoplasms is equally relevant. The study of rare tumors contributes to the understanding of the more common ones, as both could share the same hallmark genetic drivers. The identification of driver mutations in benign tumors is facilitated by the fact that they harbor quiet genomes. Pathogenic mutations have being described in benign epithelial odontogenic tumors, such as ameloblastomas and adenomatoid odontogenic tumors...

BACKGROUND: Expression of various cellular/molecular factors change during the course of tumor formation from odontogenic tissues of the tooth germ. Evaluation of these factors can help provide a better perception of the tumorigenesis and biologic behavior of odontogenic tumors (OTs). Syndecan-1 is a heparan sulfate proteoglycan which has not been extensively investigated in these lesions. The objective of the present study was to assess the immunohistochemical expression of CD138 in adenomatoid odontogenic tumor (AOT), ameloblastic fibroma (AF) and odontogenic myxoma (OM) and to compare it with ameloblastoma and keratocystic odontogenic tumor (KCOT)...

Glandular lesions that cannot be diagnosed readily as salivary gland tumors occur uncommonly in the upper aerodigestive tract. They occur only with some frequency within the sinonasal tract. Well-characterized lesions at this site include the respiratory epithelial adenomatoid hamartoma, seromucinous hamartoma, and intestinal and non-intestinal-type adenocarcinomas. This article reviews the clinicopathologic features of these fascinating lesions.

Adenomatoid tumors are neoplasms of mesothelial origin, usually occurring in the male and female genital tracts. Extragenital localization sites such as adrenal glands are rare but have been reported. When found in the adrenals, they represent great clinical, radiological and pathological diagnostic challenge, with wide range of differential diagnoses to be considered. We present a case of a 30 years old female, with incidental ultrasound finding of unilateral tumor in the right adrenal gland. Multi slices CT scan was of value in localizing this tumor, but not in the precise diagnosis...

Adenomatoid tumor is an uncommon benign mesothelial neoplasm, usually localized in the epididymis. It is the most common paratesticular tumor of middle-aged patients (average age of clinical presentation: 36 years). However, these tumors in pediatric and pubertal patients are extremely rare. Due to their rarity, we present a case of adenomatoid tumor of the tail of the epididymis in a 16-year-old patient. After systematic research of the current literature, we did not find another case report of epididymal adenomatoid tumor in a male patient aged 16 years old or less...

BACKGROUND: Uterine leiomyomas are common uterine tumors, and typical cases of leiomyoma are easily diagnosed by imaging study. However, uterine leiomyomas are often altered by degenerative changes, which can cause difficulty and confusion in their clinical diagnosis. We describe the 17th reported case of a uterine leiomyoma clinically diagnosed as an ovarian tumor; however, the present case shows the most detailed radiological evaluation, including contrast-enhanced magnetic resonance imaging...

Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin and often misdiagnosed as an odontogenic cyst. It is predominantly found in young female patients, located more often in maxilla, and in most cases associated with an unerupted permanent tooth. There are three variants of AOT namely follicular, extra follicular, and peripheral. We report an unusual case of extrafollicular AOT in maxilla of a 50-year old male patient.
