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.

Introduction. Hepatobiliary cystadenomas are rare benign cystic tumors and have a potential for recurrence and malignant transformation. The diagnosis may be very difficult because of absence of typical imaging feature in some cases.Case Presentation. In this paper, the authors discuss a 57-year-old woman who presented a jaundice related to hepatobiliary cystadenoma. Biological and radiological examinations have led to surgery, and the diagnosis is made after a histological examination of surgical specimens.Conclusion. This observation illustrates a hepatobiliary cystadenoma revealed by jaundice. Histology examination contributed to diagnosis. The authors discussed the mechanisms of biliary obstruction and differential diagnoses through a review of the literature.

Abstract Background Terminal deletion of chromosome 10p is a rare chromosomal abnormality. We report a neonatal case with a large deletion of 10p15.3p13 diagnosed early because of severe clinical manifestations. Case presentation Our patient presented with specific facial features, hypoparathyroidism, sen sorineural deafness, renal abnormalities, and developmental retardation, and carried a 12.6 Mb deletion in the 10p15.3 p13 region. The terminal 10p deletion involved in our patient is the second largest reported terminal deletion reported to date, and includes the ZMYND11 and GATA3 genes and a partial critical region of the DiGeorge syndrome 2 gene (DGS2). Conclusion On the basis of a literature review, this terminal 10p deletion in the present case is responsible for a specific contiguous gene syndrome. This rare case may help the understanding of the genotype–phenotype spectrum of terminal deletion of chromosome 10p.

Evidence Level

Thrombosed urethral prolapse is a rare clinical condition. In this context, we describe our experience and compare our findings with the literature, following presentation of five consecutive cases over 2 years. This will hopefully improve awareness and appropriateness of specialty referrals as a correct diagnosis is rarely established prior to the patient being seen by a urologist. We also wish to highlight a case presentation of thrombosed urethral prolapse outside the bimodal age distribution which has been recorded in the literature. Level of Evidence: Level 4

Tumour Reduction

Giant condyloma acuminatum or Buschke-Lowenstein tumour is a very rare disease which usually is located in the genital, anorectal, and perianal regions. It is regarded as a type of verrucous carcinoma occurring on anogenital mucosal surfaces where it is locally invasive but displays a benign cytology. We describe a case of a 24-year-old woman with persisting condyloma acuminata progressing to a large intra-abdominal Buschke-Lowenstein tumour. To our knowledge such an advanced stage has only been reported once before. The severity and extent of the tumour both determine the treatment and patient outcome. Treatment was impeded by cachexia, an immunosuppressive state after kidney transplantation and difficulties in establishing a reliable diagnose. Interferon treatment was started which initially led to tumour reduction but was complicated by an interferon-induced pancreatitis, pneumonia, and fasciitis necroticans resulting in death. We present a literature overview on the treatment options for a Buschke-Lowenstein tumour, with emphasis on interferon therapy, with all the advantages and disadvantages.

<b><i>Introduction:</i></b> Extraneural metastases of glioblastoma are very rare clinical entities, especially in pediatric patients. Because of their rarity, they can be confused with other pathological processes. <b><i>Case Presentation:</i></b> We report a case of 16-year-old boy with extensive extraneural metastases of glioblastoma. Lung, liver, cervical lymph nodes, skin, and bone metastases were detected in the patient. <b><i>Conclusion:</i></b> We describe the presentation, evaluation, and diagnosis of this rare condition with regard to pertinent literature.

Introduction. Radiation recall dermatitis (RRD) is a phenomenon that occurs in previously irradiated areas shortly after administration of a chemotherapeutic agent. As the use of sorafenib expands, the incidence of radiation recall dermatitis induced by sorafenib will likely increase. Here, we report on a patient who developed RRD and describe his clinical characteristics along with a review of the literature. Case Presentation. Our patient was treated with palliative radiation therapy (RT) to a painful metastatic hepatocellular carcinoma lesion in the right forearm. He completed his radiation course with grade 1 dermatitis, which had resolved by the time he was started on sorafenib 400 mg twice daily 7 days afterwards. On the 21st day after RT, he presented with desquamation and erythema in the previously irradiated area of the right forearm, consistent with RRD. The sorafenib was discontinued and his symptoms subsequently resolved with conservative topical management. Conclusions. Although the pathophysiologic mechanism of sorafenib-related radiation recall dermatitis remains to be investigated, practitioners should be aware of its presence and management in order to improve clinical outcomes.

Melanoma Case

Background: Nevus spilus is characterized by a pigmented patch with scattered flat or maculopapular speckles. Nevus spilus was first described by Burkley in 1842. Since then, this lesion has been widely debated in the literature, particularly for the possible occurrence of melanoma within the lesion. Objective: We describe the case of a 65-year-old female presenting with a nodular achromic melanoma that occurred within a nevus spilus on the left thigh. Conclusion: Our observation is consistent with the idea that this entity in some circumstances may have the ability to evolve into a malignant melanoma.
