A Case Presentation of Well-Differentiated Hepatocellular Carcinoma With No Sign of Liver Disease.

The type of liver cancer that occurs most frequently is hepatocellular carcinoma (HCC). The majority of cases of HCC are secondary to alcoholic cirrhosis or viral hepatitis. The presence of malignant cells with modest nuclear atypia that resemble normal hepatocytes and the lack of bare nuclei in the smears, which shows the neoplastic hepatocytes' capacity, are characteristics of a well-differentiated HCC plasma membrane to tolerate smearing. We present the case of an 83-year-old male patient with a well-differentiated HCC, who had no etiological factors and no signs of alcohol cirrhotic liver, or any symptoms of liver disease which are the main causes of the HCC.

A Misdiagnosed Case of Malignant Melanoma in an Infected Nail: A Case Report.

Subungual melanoma is associated with the highest mortality among all skin cancers and is strongly linked to acquired mutations caused by exposure to ultraviolet radiation in sunlight. The commonest sites of occurrence are the great toe and thumb. Diagnosis of melanoma often becomes a challenge as it is difficult to differentiate it from other pigmented disorders. A histopathological evaluation of the lesion with adequate nail matrix biopsy can address the diagnostic dilemma. Additionally, an early diagnosis of melanoma is critical as once detected early, it is often treatable. We present a case of a 72-year-old diabetic male patient with a pigmented lesion over the right great toe. In view of the patient's age and history of diabetes, the initial presentation was mistaken as onychomycosis which created a diagnostic dilemma. Hence, we present this case to shed light upon the fact that these lesions can mimic several other benign conditions like fungal melanonychia, lentigo, and subungual hemorrhage. To avoid misdiagnosis and subsequent delay in management, early clinical, dermoscopic, and very pertinently, histopathological and radiological co-relations are extremely important.

Beyond the Norm: Navigating a Unique Papillary Carcinoma Journey in Breast Cancer.

The presence of papillary structures inside the tumor is a unique and uncommon characteristic of breast cancer, and it is known as papillary carcinoma. In contrast to other forms of breast cancer, this variant usually manifests as a well-defined mass in imaging investigations and is frequently linked to a good prognosis. We present a case of a 72-year-old female with papillary carcinoma of the breast identified after presenting with a palpable breast lump. Following a left simple mastectomy and adjuvant treatment, the presence of papillary structures inside the tumor was verified by a histopathological study. Understanding the clinical and pathological characteristics of breast papillary carcinoma is crucial for precise diagnosis and suitable therapy strategizing. More research is required to further understand the molecular traits and best practices for treating this uncommon subtype of breast cancer.

A Case of Well-Differentiated Endometrial Adenocarcinoma in a Postmenopausal Woman.

Endometrial adenocarcinoma is a prevalent malignancy among postmenopausal women, often presenting with symptoms such as abnormal vaginal bleeding and pelvic pain. We present a case of a 60-year-old postmenopausal female who exhibited abnormal vaginal bleeding for three months, accompanied by pelvic pain and unintentional weight loss. Clinical evaluation, including physical examination, imaging studies, and histopathological examination, led to the diagnosis of well-differentiated endometrial adenocarcinoma. The patient underwent an abdominal hysterectomy with bilateral salpingo-oophorectomy, and histopathological analysis confirmed invasive tumor involvement in the lower uterine segment and cervix. The final pathological tumor, node, and metastasis (TNM) staging was reported as pT1b No Mx, FIGO (International Federation of Gynecology and Obstetrics) stage II. This case underscores the importance of considering endometrial adenocarcinoma in the differential diagnosis of postmenopausal bleeding and highlights the significance of timely diagnosis and multidisciplinary management for optimizing patient outcomes.

Stealthy Encroachment: Unraveling an Encounter With Renal Myelolipoma.

Myelolipoma of the kidney is an exceedingly unusual benign tumor of hematological components mixed with mature adipose tissue. We present a case of a 59-year-old male who presented with left flank pain and was found to have an atrophic left kidney on imaging studies. A computed tomography (CT) scan revealed a small and shrunken left kidney with an extrarenal pelvis. A diethylenetriamine pentaacetate (DTPA) scan results showed a total glomerular filtration rate (GFR) of 45.6 ml/min with a non-functional left kidney. The patient underwent a left nephrectomy, and a histopathological examination confirmed the diagnosis and highlighted the distinctive morphological features of this rare entity. Postoperatively, the patient experienced a complete resolution of symptoms. This case underscores the importance of considering myelolipoma in the differential diagnosis of renal masses and highlights the successful management of symptomatic cases through surgical intervention. Awareness of this rare tumor is crucial for accurate diagnosis and appropriate management. Further studies are needed to elucidate the natural history and optimal treatment strategies for renal myelolipomas.

Unusual Presentation of a Giant Cell Tumor of the Bone: A Case Report.

Bone giant cell tumors (GCTs) are rare, non-cancerous tumors that mostly affect the meta-epiphyseal region of long bones in the legs and arms. We are reporting a case of GCT of bone of a 14-year-old male; it usually occurs in the age group of 20-40 years. The presence of multinucleated giant cells and stromal cells in the proximal diaphysis of the left tibia serves as a distinguishing characteristic. The majority of GCTs are benign; they have the potential to induce bone loss and can be locally aggressive. Treatment options often include surgery, and in some cases, medications like denosumab may be used to help shrink the tumor or manage recurrent cases.

Fanconi Anemia: A Rare Genetic Disorder.

Fanconi anemia is a rare genetic disorder affecting various body systems. Congenital abnormalities, poor hematopoiesis, a higher incidence of acute myeloid leukemia, myelodysplastic syndrome, and malignancies are the hallmarks of this autosomal recessive condition. In certain instances, the clinical signs and highly diverse phenotypic presentation make a diagnosis challenging. In this case report, an eight-year-old boy presented with recurrent episodes of fever, generalized weakness and physical deformities. He had left thumb deformity, triangular face, short stature, and hyperpigmentation with café au lait spots. Bone marrow biopsy revealed hypoplastic marrow, peripheral blood smear revealed pancytopenia, and chromosomal breakage testing was also positive.

Intricacy in the Diagnosis of Retroperitoneal Angiomyolipoma: A Rare Case.

An uncommon benign mixed mesenchymal tumor called extrarenal retroperitoneal angiomyolipoma (ERAML) comprises thick-walled blood vessels, smooth muscle cells, and mature fat cells. Angiomyolipoma often develops in the kidneys, with extrarenal locations being uncommon. Many angiomyolipomas are unintentionally discovered when a person undergoes other medical issues. A 35-year-old man presented with a history of difficulty breathing and was on antibiotics. On follow-up, CT revealed a 22.5 × 14.3 × 8.6 cm right retroperitoneal mass. The retroperitoneal mass was resected en bloc at laparotomy and sent for histopathological examination. The grossly resected specimen was a smooth, well-circumscribed, yellowish-red retroperitoneal mass measuring 23 × 15 × 9 cm. The microscopic section reveals a tumor with prominent blood vessels and fatty tissue composed of spindle cells arranged into fascicles. The final diagnosis for this case is ERAML, which was challenging to distinguish from liposarcoma.

Histopathological Diagnosis of Eumycetoma With Paraspinal Sinuses: A Rare Case Report.

Mycetoma, well known as "Madura foot," is a long-standing granulomatous infection of the skin and subcutaneous tissue. Causative organisms are filamentous fungi (eumycetes) and bacteria (actinomycetes). It characteristically presents with firm woody swelling, discharging sinuses with grains (containing the causative organism). Diagnosis in suspected cases can be made by microbiological evaluation, histopathological, cytological and radio imaging techniques. To differentiate between eumycetoma and actinomycetes histopathology is an accurate diagnostic modality as seen in the present case. We report a case of 42 years male who presented with swelling on his back with discharging sinus. Histopathological specimen containing multiple, irregular, greyish, whitish tissue pieces with skin attached all together measuring around 12×9×4 cm from the paraspinal region. The section shows histopathological features suggestive of eumycetoma. Periodic acid -Schiff stain showed the presence of septate, branching fungal hyphae and black granules. Eumycetoma can be accurately diagnosed by histopathological evaluation using a special stain. It is confirmatory and provides a guide for treatment plans with a high index of suspicion.

Correlation of Morphological Findings of Endometrium With Concerned Hormone Levels in Patients With Abnormal Uterine Bleeding: A Narrative Review.

Abnormal uterine bleeding (AUB) is a distressing menstrual condition that continues to be one of the most common rationales for hysterectomy in underdeveloped countries. It can be either focal (breakthrough bleeding) or diffuse (bleeding throughout the body) (withdrawal bleeding). AUB has a negative impact on a female's physical, social, and emotional well-being. It is caused by chronic endometritis, micro erosions, or vascular fragility caused by micro-vessel structural anomalies. Polyps, submucosal leiomyoma, atrophy, and cancer can all produce endometritis and micro erosions in otherwise healthy endometrium (organic causes). In hyperplasia and endometrial cancers, especially type I, estrogen and progesterone hormones are also expressed. The level of these hormones gives prognostic information. They also provide amenability to hormonal therapy. Hormonal imbalance is the main component involved in the pathogenesis of dysfunctional uterine bleeding (DUB).
