- Pseudoepitheliomatous Hyperplasia Mimicking Squamous Cell Carcinoma in Association with a CD30+ Lymphoproliferative Disorder
Submitted by: Dr. Jaime Colonje
A 77 year old man presented with an 8 week history of rapidly enlarging non-painful papule on left side of abdomen, initially size of a pea. Increased over next 8 weeks into an ulcerated nodule. Intermittent bleeding secondary to trauma. He had extensive cardiac problems. No other lesions, no peripheral palpable lymphadenopathy. Treated with oral and topical antibiotics without effect.
Case 3 - Figure 1

- So-called "Sclerosing Hemangioma"
Submitted by: Dr. Osamu Matsubara
The patient was a 67 years old Japanese woman with a history of sigmoidectomy for sigmoid colon cancer. Pathological examination revealed that this cancer was well differentiated adenocarcinoma with invasion into the subserosal layer. Two months later, a chest X-ray and CT scans of the thorax showed a coin lesion in the right lower lobe. She underwent tumorectomy of this lung nodule by video-assisted thoracosurgery (VATS). The clinical diagnosis was metastatic lung cancer.

- Sclerosing Adenosis of the Prostate
Submitted by: Dr. Hema Samaratunga
A 68-year-old male presented in July 2002 with an elevated PSA of 13.19 ng/ml (normal 4.5). His serum PSA had been progressively increasing since 1997, when it was 4.5. He had some associated lower urinary tract symptoms. Digital rectal examination (DRE) revealed a smooth prostate. On transrectal ultrasound (TRUS), the transition zone was enlarged and the volume was estimated to be about 85 g. He underwent a TRUS guided prostatic biopsy in August 2002, and this was reported as benign with chronic prostatitis. He continued to have urinary symptoms and his PSA continued to climb and was up to 16.9 in December 2004 when he underwent a repeat biopsy. This again showed no evidence of malignancy, but had atrophy with acute inflammatory changes. He continued to have obstructive lower urinary tract symptoms and presented for a TURP when 60 g of prostatic tissue was removed. This was reported as nodular prostatic hypertrophy with Gleason score 3+4 = 7 prostatic adenocarcinoma involving 5% of the tissue. Post operatively, his urinary symptoms improved significantly and his PSA reduced to 3.9. PSA was at about the same level when he was last seen in May 2005.

- Granulomatous Mastitis
Submitted by: Dr. Salam Al-Sam
52 year-old woman presented with a unilateral breast mass. Mammography demonstrated an ill-defined opacity. Physical examination revealed a firm/hard mass, 3 cm in size (P5 R3). Fine Needle Aspiration was performed and reported as C5 malignant. Mastectomy and axillary sampling was performed based on high clinical and cytological suspicion.
- Microglandular Adenosis in Association with Invasive Ductal Carcinoma
Submitted by: Dr. Sunil Lakani
A 72 year old woman presented with a 27mm lump in her breast. Initial investigations suspicious for malignancy, lump excised.
Case 8 - Figure 1

- Pseudosarcomatous ('Reactive') Myofibroblastic Proliferation
Submitted by: Dr. Christopher D.M. Fletcher
