Penis

Penis

  • Mal formations

  • Inflammatory conditions

  • Premalignant lesions and malignant conditions


Mal formations of penis

Mal formations of penis


Epispadias infection and urinary incontinence

Epispadias: Infection and urinary incontinence.


Inflammation of penis and prepuce

Inflammation of penis and prepuce

Banalities & Balanoprosthitis : Hyperemia and exudates.


Banalities balanoprosthitis complications phimosis and paraphimosis

Banalities & Balanoprosthitis Complications : Phimosis and Paraphimosis

Paraphimosis


Genital candidiacis

Genital candidiacis

  • Etiology: Diabetes Mellitus


Penis1

Penis

  • Premalignant lesions

  • Malignant conditions


Premalignant lesions

Premalignant lesions

  • Etiology

  • Carcinogens in smegma

  • HPV type 16


Types of premalignant lesions penis

Types of Premalignant lesions : Penis

  • Carcinoma in situ ( Following types).

    • Bowen disease (HPV type 16).

    • Erythroplasia of Queyrat (HPV type 16)

    • Bowenoid Papulosis (Etiology = Venerally transmitted diseases)


Bowen disease gross solitary plaque like lesion

Bowen disease : gross – Solitary plaque like lesion


Bowen disease micro in situ carcinoma intact basement membrane severely dysplastic epithelium

Bowen disease : micro – in situ carcinoma ; intact basement membrane ; severely dysplastic epithelium

10 % progress to invasive carcinoma


Malignant lesion pf penis

Etiology

Types of malignancy

Morphology

Clinical features

Squamous cell carcinoma

Verrucous carcinoma

Malignant lesion pf Penis


Etiology of carcinoma penis

Etiology of carcinoma penis

  • Carcinogens in smegma

  • HPV type 16


Squamous cells carcinoma penis

Squamous cells carcinoma : penis

This is a squamous cell carcinoma of the penis ( penectomy specimen )


Keratinized squamous cell carcinoma

Keratinized squamous cell carcinoma


Verrucous carcinoma papillary growth pattern good prognosis

Verrucous carcinoma : Papillary growth pattern- good prognosis.


Scrotun testis and epididymis

Scrotun , Testis and epididymis

  • Cryptorchidism

  • Inflammatory conditions of testis

  • Male infertility

  • Hydrocele

  • Hematocele, chylocele, elephantiasis

  • Testicular torsion


Cryptorchidism definition

Cryptorchidism : Definition

  • Definition: crypto=hidden, orchid= testicle,

  • Testis fails to descend in the scrotum by age 12 months.

  • Cause:

  • Hormonal abnormality

  • Intrinsic testicular abnormality.

  • Mechanical obstruction in inguinal canal.


Morphology testicular atrophy

Morphology ( Testicular atrophy)

  • Right testis more commonly involves. Small testis.

  • Tubular atrophy with hyalinization present.


Microscopy of atrophic tubules diffuse of testis

Microscopy of Atrophic Tubules ( diffuse) of testis.


Complication cryptorchidism

Complication ; Cryptorchidism

  • Infertility

  • Seminoma ( malignancy) particularly with unilateral undescended testis.


Causes of testiculate atrophy and that may lead to infertility

Causes of testiculate atrophy and that may lead to Infertility

  • Cryptoorchitism ( unilateral / bilateral).

  • Chronic alcoholism ( Bilateral)

  • Chronic Ischemia ( unilateral / bilateral)

  • Chemotherapy or radiation ( Bilateral)

  • Mumps orchitis ( focal atrophy)

Never forget


Inflammatory lesion of testis

Inflammatory lesion of testis

  • Epididymitis

  • Orchitis.


Testis infection

Testis : infection


Orchitis

Orchitis.

Etiology

  • Mumps ( mumps orchitis ) : common in adult.

  • Plasma cells and lymphocytes are present.


Focal atrophy of the testis tubules mumps orchitis

Focal atrophy of the testis tubules ; Mumps orchitis

NORMAL


Laboratory

Laboratory

  • Sperm count will be low BUT not NIL.

  • Infertility do not occur usually.


Tuberculosis

Tuberculosis

  • Epithelioid cell granuloma is present with cassation necrosis.


Causes of male infertility 1 of 2

Causes of Male Infertility 1 of 2

  • Mumps (unilateral / Bilateral)- temporary infertility.

  • Cryptoorchitism ( unilateral / bilateral).

  • Chronic alcoholism ( Bilateral)

  • Chronic Ischemia ( unilateral / bilateral)

  • Chemotherapy or radiation ( Bilateral)

  • Hydrocele and Varicocele

Never forget


Other causes of male infertility 2 of 2

Other causes of male infertility 2 of 2

  • Klienfelter syndrome : patient present with gyenecomastia.

  • Sertoli cell-only syndrome : No Sperm-Producing Cells, tubules contain only Sertoli cells.


Sertoli cell only syndrome sperm count nil

Sertoli cell-only syndrome; sperm count NIL.


Hydrocele etiology

Hydrocele : etiology

  • Inflammation

  • Idiopathic


Hydrocele accumulation of serous fluid in tunica vaginalis

Hydrocele : Accumulation of serous fluid in tunica vaginalis.


Hematocele chylocele elephantiasis

Hematocele, chylocele, elephantiasis

  • Hematocele : blood in tunica vaginalis ( in trauma)

  • Chylocele : lymph in tunica vaginalis ( in lymphatic obstruction).

  • Elephantiasis : in filarial infection ( lymphatic obstruction).


Elephantiasis

Elephantiasis


Varicocele dilation of the pampiniform plexus

Varicocele : Dilation of the pampiniform plexus

Complication : infertility


Testicular torsion hemorrhagic infarction

Testicular torsion : hemorrhagic infarction

Etiology : Trauma or tumor in the testis


Testis

Testis
