Rare Lesion

Mesenchymal type tumors originated in the submucosa represent a small percentage of colorectal polyps. This is particularly true for polyps composed of more than one mesenchymal tissue type. We herein present the pathological features of an unusual polypoid proliferation of mature fatty, fibrous, and vascular tissues including vessels of diverse nature and size. The histological findings support a hamartomatous rather than a true neoplastic origin for this rare lesion.

Mesenchymal Tissue

Most of the colonic submucosal mesenchymal polyps are benign tumors. They are formed by more than one type of mesenchymal tissue. The diagnosis of angiolipofibroma depends on the histological findings with the proliferation of vascular, fatty, and fibrous connective tissues. Majority of angiolipofibromas are arising in the kidney and have rare presentation as extra renal region. Here we report a case of 58-year-old female patient with angiolipofibroma of sigmoid colon (8.5 cm x 4 cm size) which was treated successfully with surgical resection. The clinical presentation, operative procedure, pathological features, and medical literature review are presented.

Genetic Features

Many soft tissue tumors of childhood lack obvious differentiation toward a defined mesenchymal tissue type or have a phenotype that does not correspond to any defined normal tissue. These challenging tumors are currently regarded as neoplasms of uncertain differentiation. Nonetheless, there have been great strides in the understanding of their pathologic and genetic features and biologic underpinnings. The application of new genetic information to the pathologic diagnosis among this group of tumors is an emerging area in diagnostic pediatric pathology. This article reviews the clinicopathologic features of tumors of uncertain and/or miscellaneous origin, with an emphasis on the unique aspects of these neoplasms in children and adolescents, use of diagnostic adjuncts, and differential diagnosis.

Clinical And Pathological Features

Hepatoid adenocarcinoma of the lung (HAL) is an comparatively rare malignant tumor originating from the lung with shorter survival. HAL morphologically and pathologically exhibits hepatocellular carcinoma (HCC)-like characteristics, while its clinical features resemble pulmonary adenocarcinoma. High concentration of alpha-fetoprotein (AFP) is often detected in the serum of HAL patients with no hepatic occupying lesion. Patients with AFP-negative HAL survive a few months longer than those with positive AFP test. HAL is a rare type of carcinoma, so there is a lack of systematic and extensive statistical research. The treatment strategy for HAL is similar to common lung adenocarcinoma. Complete surgical resection and adjuvant chemotherapy are the current major treatments for HAL patients. There are also a few of case reports suggesting that HAL patients may benefit from immunotherapy and targeted therapy. This review focuses on the clinical and pathological features, immunohistochemical staining characteristics, treatment and prognosis of HAL.

Abstract A basal cell ameloblastoma is an uncommon benign neoplasm and has a similar histological appearance to basal cell carcinoma of the skin. This clinical case report will discuss an ameloblastoma originating in the maxilla and of the baseloid variant. The objective of report is to highlight the possibility of misdiagnosis from this challenging case. A 34-year-old male was referred to the maxillofacial department with recurrent nasal regurgitation following dental extraction from the left maxilla 1 year previous. Clinically there was an oro-antral fistula visible and initial CT showed cystic lesion in the left maxilla likely to represent an odontogenic cyst. The patient underwent extraction and enucleation, where the diagnosis of the amelobalstoma was established with need of resection. Partial maxillectomy and primary closure with buccal fadpad was performed in the second stage and histological results showed a 6mm completely excised basal cell carcinoma within the oral mucosa and no bony invasion. Due to this extremely unusual results, secondary histological review was requested, and conclusion was a fully excised basal cell ameloblastoma. Following the procedure and subsequent reviews, the patient has no evidence of oro-antral fistula or recurrence of this rare type of neoplasm. A basal cell ameloblastoma variant is a rare lesion and due to its’ similar histological appearance to a basal cell carcinoma, can lead to a misdiagnosis. The aim of the report is to show the unusual presentation and findings along the way to correct diagnosis in this case.

Abstract Background and study aims Few studies have evaluated detection of pancreatic carcinoma in situ (PCIS). We evaluated findings of endoscopic ultrasound (EUS) and pathological features of PCIS. Patients and methods We histopathologically studied 16 patients with PCIS following EUS. Diagnostic features evaluated retrospectively included stricture of the main pancreatic duct (MPD) on EUS, presence or absence of hypoechoic areas surrounding the MPD stricture on EUS, the noncancerous part (pancreas of background) on EUS and histopathology, and histological findings adjacent to the area of PCIS. Results On EUS, stricture of the MPD was found in 15 patients (93.8 %). Hypoechoic areas surrounding the MPD stricture were observed in 9 patients (56.3 %), including three (18.8 %) with a 10- to 11-mm hypoechoic mass. EUS findings of the noncancerous part indicated chronic pancreatitis in six patients (37.5 %), pancreatic fatty infiltration in seven (43.8 %), early chronic pancreatitis in two (12.5 %), and normal pancreas in one (6.3 %). Histological findings of the noncancerous part (proximal to the MPD stricture) indicated chronic pancreatitis in 13 patients (81.3 %) and pancreatic fatty infiltration in five patients (31.3 %). Histopathologically, subepithelial inflammatory cell infiltration and fibrosis were present in all 16 patients with PCIS. Conclusions PCIS frequently causes localized changes in inflammation and fibrosis around the pancreatic duct. PCIS often accompanies chronic pancreatitis and pancreatic fatty infiltration in the background of the pancreas. EUS offers sufficient resolution to demonstrate pancreatic changes of PCIS.

Solid Papillary Carcinoma

Solid papillary breast carcinoma is a rare type of breast carcinoma. We present four cases which highlight the radiological and histological findings of solid papillary carcinoma. Mammogram supplemented with ultrasound played an important role in detecting solid papillary carcinomas which usually presents as intraductal lesions or intracystic mass with Doppler signal. Excision biopsy is a better option than core biopsy as the latter modality may not be representative and the diagnosis of solid papillary breast carcinoma may be missed.

Porocarcinoma is a very rare type of skin cancer arising from the eccrine sweat glands and is poorly understood. The exact pathogenesis is unknown. Clinical features are non-specific. It may present as a painless, slow growing mass or nodule, ulcer, plaque, swelling, wart, papule or naevus that increases in size over years to decades and may ulcerate or bleed upon trauma. They occur equally in both sexes and are most commonly found in the lower extremity. Though metastasis is rare, they are considered aggressive with high mortality rate. Diagnosis requires standard histopathological studies. Immunohistochemistry is useful in difficult cases. Treated early, eccrine porocarcinoma is curable by wide excision. The author reports the case of an eccrine porocarcinoma in the lower extremity of an elderly lady and a summary of its clinical, radiological and histological findings is illustrated.

Unusual Occurrence

A pilonidal sinus is a chronic inflammatory process, the etiology of which is still not fully elucidated. It frequently presents at the sacrococcygeal region (typical) and rarely at extrasacrococcygeal (atypical) locations, including the interdigital, axillary, inguinal, and umbilical regions, as well as the neck, face, and scalp. A 46-year-old man presented with a thirty-year history of a slowly growing nodule on the postauricular area of the scalp. The lesion was excised and diagnosed as a pilonidal sinus based on the clinical and histological findings. The purpose of this review is to report the unusual occurrence of a pilonidal sinus on the scalp and to review the literature regarding this particular location of occurrence.

Hepatoid adenocarcinoma (HAC) is defined as an extrahepatic tumor with hepatocyte differentiation. Hepatoid adenocarcinoma of the stomach (HAS) is a rare type of gastric cancer characterized by unique clinico-pathological features and a poor prognosis. We report a case of a metastatic HAS with a review of the literature.
