Summary
Penile pyoderma gangrenosum, a rare inflammatory condition, can be diagnosed via biopsy. Steroid treatment effectively resolved symptoms and prevented recurrence in a 77-year-old male patient.
Area of Science:
- Urology
- Dermatology
- Pathology
Background:
- Pyoderma gangrenosum is a non-bacterial inflammatory condition causing ulcers and abscesses.
- Penile pyoderma gangrenosum can be worsened by surgical intervention for abscesses.
- Differential diagnosis for penile lesions includes cancer and infections.
Purpose of the Study:
- To report a case of penile pyoderma gangrenosum diagnosed minimally invasively.
- To highlight the efficacy of steroid therapy in managing penile pyoderma gangrenosum.
- To emphasize the importance of biopsy in differentiating penile conditions.
Main Methods:
- Clinical presentation and laboratory tests were used to rule out infection and malignancy.
- Magnetic resonance imaging identified fluid accumulation in the corpora cavernosa.
- Penile biopsy confirmed an abscess and ruled out malignancy.
Main Results:
- Biopsy revealed an abscess, not cancer.
- Steroid therapy led to rapid symptomatic improvement.
- The patient remained asymptomatic after 18 months of treatment and steroid discontinuation.
Conclusions:
- Minimally invasive diagnosis via biopsy is feasible for penile pyoderma gangrenosum.
- Steroid therapy is an effective treatment for penile pyoderma gangrenosum.
- Early diagnosis and appropriate treatment prevent recurrence and complications.

Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
