Dynamic crosstalk within the tumor microenvironment of uterine cervical carcinoma: baseline network, iatrogenic alterations, and translational implications.

Uterine cervical cancer is the fourth most frequent gynecological tumor worldwide. The tumor microenvironment of cervical cancer is the result of persistent high-risk human papillomavirus infection together with stromal activation of estrogen receptor alpha and the pro-angiogenic and pro-inflammatory activity of immune cells, mainly T-helper 17 cells and tumor-associated macrophages. Therapeutic management (e.g., immunotherapy, especially in advanced cases) may be influenced by the translational implications of tumoral stroma crosstalk and an abundance of tumor-infiltrating lymphocytes within the tumor microenvironment. The prognosis of cervical cancer is inversely correlated with microvessel density, making anti-angiogenic strategies with agents such as bevacizumab crucial for improving both progression-free survival and overall survival in patients with advanced and recurrent tumors

Peritoneal Tuberculosis Mimicking Ovarian Cancer: Gynecologic Ultrasound Evaluation with Histopathological Confirmation

Peritoneal tuberculosis (TBP) is a very rare condition, accounting for about 1–2% of all tuberculosis cases. The diagnosis of TBP can be easily mistaken for advanced ovarian cancer (AOC) or peritoneal carcinoma because of overlapping laboratory and clinical findings. We reported the ultrasound characteristics of a case of TBP in a 67-year-old woman who presented to our institute with a 1-month history of intermittent lower abdominal pain, fever, and asthenia. Overall, 20 biopsy-retrieved specimen histopathological features were suggestive of peritoneal tuberculosis. Gynecologic ultrasound revealed increased adnexa with multiple nodular formations spread across the surface, suggestive of caseous nodules. Although this is a rare occurrence, clinicians should consider TBP as a differential diagnosis of ovarian or peritoneal cancer

Skin Mycetoma in an 11-Year-Old African Boy: Case Presentation with Emphasis on Histopathological Features and Differential Diagnosis

Mycetoma is an uncommon, chronic infective disease of the skin and subcutaneous tissues, characterized by the triad of tumefaction, draining sinuses, and the presence in the exudate of colonial grains. In cases of long-term disease, the presence of colonial grains together with the host's derivative material can lead to the formation of real sinuses. Histological analysis is of fundamental importance to allow an accurate etiological diagnosis and to understand if the basic pathogen is an actinomycete (bacterium) or a real fungus (eumycetic mycetomas) and is also fundamental for therapy, which is quite different. Here, we present a case of Mycetoma in an 11-year-old patient who emigrated from Djibouti, Somalia, and showed the essential histopathological features of this rare and forgotten nosographic entity in the industrialized world and briefly discuss the major and most important differential diagnoses

Dedifferentiated Melanoma: A Diagnostic Histological Pitfall! Review of the Literature with Case Presentation

Dedifferentiated melanoma is a particular form of malignant melanoma with a progressive worsening of the patient's clinical outcome. It is well known that melanoma can assume different histo-morphological patterns, to which specific genetic signatures correspond, sometimes but not always. In this review we address the diagnostic difficulties in correctly recognizing this entity, discuss the major differential diagnoses of interest to the dermatopathologist, and conduct a review of the literature with particular attention and emphasis on the latest molecular discoveries regarding the dedifferentiation/undifferentiation mechanism and more advanced therapeutic approaches

Turner Syndrome Mosaicism 45,X/46,XY with Genital Ambiguity and Duchenne Muscular Dystrophy:Translational Approach of a Rare Italian Case

Turner syndrome (gonadal dysgenesis with short stature and sterility) is characterized by chromosomal karyotype 45,X in 50% of cases or by mosaicism (45,X/46,XX and 45,X/46,XY) in 30–40% or X structural defects (deletions, long arm isochromosome, ring chromosome). When mosaic Turner syndrome (TS) occurs with a Y chromosome, there may be ambiguous genitalia. Duchenne muscular dystrophy (DMD) is an inherited neuromuscular disease with an X-Linked recessive pattern of inheritance that predominantly affects males, while females are usually asymptomatic. DMD has also been observed in groups of females affected by TS, not homozygous for the mutation. Here, we report a case of an Indian neonate born with ambiguous genitalia diagnosed prenatally by ultrasound who had a karyotype of 45,X/46,XY and who also had Duchenne muscular dystrophy caused by a de novo mutation in the DMD gene. Physical examination was normal without the typical dysmorphic features of TS with the exception of the genitourinary system showing ambiguous genitalia. Gender was assigned as female. At the age of three years, she had increasing difficulty walking, running, jumping and climbing stairs, proximal upper and lower extremity muscle weakness and a positive Gowers’ sign. In addition, the serum creatine kinase (CK) value was over 30X the upper limit of normal. This study shows that DMD can occur in females with TS having 45,X/46,XY mosaicism and that this coexistence should be considered in women affected by TS who start to develop potential typical symptoms such as motor or developmental delay
