A congenital megalourethra is an enlargement of the pendulous urethra without evidence of distal obstruction. A 1-month-old boy presented to us with complaint of weak stream, ballooning of the penis before and during voiding and post voiding dribbling, since birth. Physical examination and cystourethroscope confirmed the diagnosis of congenital scaphoid megalourethra. He underwent reduction urethroplasty. During postoperative follow up, he had normal looking penis with good urinary stream.

Aggressive angiomyxoma is a rare benign mesenchymal stromal tumour, characterized by locally infiltrative nature and a tendency for recurrence. Only a few cases of penile involvement have been reported in the literature so far. We report a case of aggressive penile angiomyxoma in a sixty-two-year-old obese, diabetic male patient. He presented with obstructive lower urinary tract symptoms (LUTS) and diffuse enlargement of the penis and scrotum. He was managed with excision, reduction scrotoplasty, internal urethrotomy, followed by Leuprolide therapy for prevention of recurrence...

Limnodrilus species are annelid worms distributed worldwide in various freshwater sediments. The systematics of Limnodrilus has chiefly been based on morphology, but the genus has not been subject to any closer phylogenetic studies over the past two decades. To reconstruct the evolutionary history of Limnodrilus, and to assess the monophyly of this genus and its systematic position within the subfamily Tubificinae (Annelida: Clitellata: Naididae), 45 Limnodrilus specimens, representing 19 species, and 35 other naidid species (representing 24 genera) were sampled...

The luteinizing hormone receptor (LHCGR) is necessary for fertility and genetic mutations cause defects in reproductive development and function. Activating mutations in LHCGR cause familial male limited precocious puberty (FMPP). We have previously characterized a mouse model (KiLHRD582G) for FMPP that exhibits the same phenotype of precocious puberty, Leydig cell hyperplasia and elevated testosterone as boys with the disorder. We observed that KiLHRD582G male mice became infertile by 6 months of age although sperm count and motility were normal...

A 45-year-old farmer presented with ulcers and plaques over his scrotum for the past 4 to 5 years. The condition started as a small lesion on the shaft of the penis, which improved with treatment; however, after 2 to 3 months, papulonodular lesions developed on the scrotum, which increased in size and subsequently broke down to form ulcers. He denied drug abuse but had a history of multiple unprotected sexual exposures. He was prescribed oral antibiotics, which improved the lesions, but he failed to take the antibiotics for more than a week...

We present the case of a 43-year-old white man with a complex lesion at the base of the penis that combines features of both a poroma and a condyloma with human papillomavirus (HPV) infection, atypias, and focal ductal differentiation. It was a papillomatous lesion with epidermal hyperplasia, which mainly contained focally pigmented monotonous basaloid cells. Ductal lumina with cuticular cells were easily identified. Atypias were focally evidenced, with nuclear enlargement and hyperchromasia. Hypergranulosis and koilocytosis were also present...

Injection of the subcutaneous tissues of the penis for enlargement of penile girth has been practised for many years by laypeople and medical practitioners alike. However, with recognition of the complications, the practice has died out. We report a series of five patients who presented having injected foreign materials into the subcutaneous tissues of their penises, including paraffin and mineral oils. Our patients had a variable time course of presentation ranging from 1 day following injection to over 26 years...

A penile tumor (4 × 2.5 × 1 cm) was surgically removed from an African pygmy hedgehog (Atelerix albiventris) aged 3 years and 5 months. The tumor was continuous with the dorsal fascia of the penile head. Histopathologically, tumor cells were pleomorphic (oval-, short spindle- and star-shaped cells) with low cell density. Abundant edematous stroma was weakly positive for Alcian blue staining and positive for colloidal iron reaction. Tumor cells displayed no cellular atypia or karyokinesis. Tumor cell cytoplasm was positive for vimentin antibody, while cytoplasm and nuclei were positive for S-100 protein antibody...

Acquired scrotal giant muscular hamartoma is an uncommon benign lesion with fewer than 10 documented cases all over the world. It is characterized by a proliferation of dermal smooth muscle bundles of scrotum dartos fascia. The authors report a rare case of acquired scrotal giant muscular hamartoma, which occurred in a 70-year-old severely obese and diabetic man presenting with a progressive scrotal enlargement and swelling in the last year, causing marked reduction in quality of life and cosmetic problems...

A 50-year-old man presented to the genitourinary medicine clinic with a 3-year history of skin-colored circular papules over the shaft and glans of the penis. There were multiple lesions that were initially small, around 0.3 cm in diameter, and gradually enlarged. Physical examination revealed five nodules over the glans and shaft of the penis, with the largest lesion measuring 3×1 cm over the lateral aspect of the shaft (Figure 1). There were no similar lesions elsewhere. There was no lymphadenopathy and the rest of the examination was unremarkable...

Lymphedema of the penis and scrotum is a rare entity characterized by enlargement of the skin and subcutaneous tissue of the genital region due to lymphatic drainage impairment. This clinical condition is more frequent in tropical countries due to a higher incidence of filariasis, which, in turn, is the main etiology. We describe the case of a 33-year-old man with large lymphedema of the scrotum and penis due to an acute and chronic inflammatory process, foreign body granuloma, and marked hyalinization. Four consecutive surgical interventions were necessary to remove the great part of the affected tissue, which enabled satisfactory results and improved the patient's quality of life...

Testicular or ovotesticular disorder of sex development (DSD) in genetic females (78,XX; SRY-negative) has been reported quite frequently in numerous dog breeds and is usually diagnosed due to the presence of female external genitalia with an enlarged clitoris. The molecular background of this disorder, diagnosed also in human and other mammals, is not fully understood. However, it has recently been proposed that a copy number variation (CNV) in the region upstream of the SOX9 gene is associated with it. We described a rare case of this disorder in a French Bulldog with abdominal testes and male external genitalia (a slightly malformed penis)...

Background. Tuberculosis of the penis (TBP) is rare. Aim. To review the literature. Method. Various internet data bases were searched. Literature Review. TBP could be primary or secondary, may develop following circumcision performed by a person who had pulmonary Tb, and may be transmitted to the penis from ejaculation, contamination from clothing, or from contact with endometrial secretions, following an earlier pulmonary Tb or Tb elsewhere. TBP presents with a painless/painful small nodule, ulcer, mass on penis which gradually enlarges, and induration/swelling of penis, with or without erectile dysfunction...

Congenital adrenal hyperplasia (CAH) due to steroid 11β-hydroxylase deficiency is the second most common form of CAH, resulting from a mutation in the CYP11B1 gene. Steroid 11β-hydroxylase deficiency results in excessive mineralcorticoids and androgen production leading to hypertension, precocious puberty with acne, enlarged penis, and hyperpigmentation of scrotum of genetically male infants. In the present study, we reported 3 male cases from a Saudi family who presented with penile enlargement, progressive darkness of skin, hypertension, and cardiomyopathy...

Tuberculous chancre is an extremely rare form of cutaneous tuberculosis. The genital area is a possible site of presentation. We present a case of a young male with a persistent balanopreputial ulceration resembling a luetic chancre with negative serology for syphilis. The diagnosis was based on the specific pathologic features and the positive intradermal reaction to tuberculin. A successful treatment was achieved by combining antituberculosis treatment and surgical approach with circumcision. After six months of antituberculosis treatment, the patient developed paradoxical inguinal lymph node enlargement, which, after surgical excision and biopsy, was not followed by a relapse of the disease and needed no further therapy...

Adrenocortical carcinoma (ACC) in pediatric and adolescent patients is rare, and it is associated with various clinical symptoms. We introduce the case of an 8-year-old boy with ACC who presented with peripheral precocious puberty at his first visit. He displayed penis enlargement with pubic hair and facial acne. His serum adrenal androgen levels were elevated, and abdominal computed tomography revealed a right suprarenal mass. After complete surgical resection, the histological diagnosis was ACC. Two months after surgical removal of the mass, he subsequently developed central precocious puberty...

A 70-year-old man presented with a slowly enlarging glans penis lesion measuring approximately 3 × 2 × 2 cm. On examination, the lesion was indurated with no induration of the glans penis deep to the lesion. He had no palpable lymphadenopathy. A glans sparing surgical excision was performed. Pathology demonstrated a squamoproliferative lesion with hyperkeratosis, and deep margin biopsy demonstrated no carcinoma. Cutaneous penile horns are hyperkeratotic lesions and may be associated with synchronous or metachronous squamous cell carcinoma...

Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease which is characterized by a deficiency of one of the enzymes involved in the synthesis of cortisol from cholesterol by the adrenal cortex. CAH cases arising from impaired 11β-hydroxylase are the second most common form. Mutations in the CYP11B1 gene are the cause of 11β-hydroxylase deficiency. This study was performed on a patient with congenital adrenal hyperplasia and with premature development such as enlarged penis, muscle development, high blood pressure, and bone age equivalent of 5 years old at 2 years of chronological age...
