Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).

Question: Abstract: We report a 59-year-old, dark-complexioned black man with a giant basal cell carcinoma infiltrating virtually the entire scalp. Widespread metastatic bone marrow involvement produced a myelophthisic anemia. Basal cell carcinoma is rare in blacks, is rarely this large, and very rarely produces myelophthisic anemia from bone marrow metastases.
Which is the apt title for the abstract? option1: Giant basal cell carcinoma with metastases and myelophthisic anemia. option2: Frozen shoulder.

Answer: Giant basal cell carcinoma with metastases and myelophthisic anemia.

Question: Abstract: The St Georg modular knee replacement has been studied in 59 cases with an observation period ranging from 28 to 73 months. In 47% of the knees both compartments were replaced; five of the six poor results were in this group. These were revised to a hinge arthroplasty or, in one case, to an arthrodesis. Other complications were few and insignificant. There were no infections. We concluded that unicompartmental knee arthroplasty can be recommended when joint involvement is localised to one compartment only. With more generalised joint disease we prefer a semiconstrained total condylar prosthesis.
Which is the apt title for the abstract? option1: St Georg modular knee prosthesis. A two-and-a-half to six-year follow-up. option2: Angiofibroma: treatment trends in 150 patients during 40 years.

Answer: St Georg modular knee prosthesis. A two-and-a-half to six-year follow-up.

Question: Abstract: Twelve (34%) of thirty-five patients with an active infection on the palms or soles caused by Hendersonula toruloidea or Scytalidium hyalinum were found to have circulating antibodies to these organisms by counter immunoelectrophoresis or immunodiffusion, compared with 9% of uninfected controls. In every instance there was cross-reactivity between the positive patients' sera and the heterologous non-dermatophyte antigen. Using crossed and intermediate gel immunoelectrophoresis it was found that cytoplasmic extracts of H. toruloidea and S. hyalinum showed 34 and 41 precipitin peaks respectively, most of which were shared by both organisms. No cross-reactions were observed between the non-dermatophyte cytoplasmic extracts and hyperimmune animal antisera raised to Trichophyton rubrum, Trichophyton interdigitale, Aspergillus fumigatus or Candida albicans. Exoantigens prepared from the two non-dermatophytes showed similar cross-reactivity between the two species. It appears that H. toruloidea and S. hyalinum are very similar in antigenic structure, a finding which lends support to the view that they may be closely related. They are also antigenically distinct from other pathogenic fungi which commonly infect skin, a fact which may be useful in their cultural identification as well as their recognition in tissue specimens.
Which is the apt title for the abstract? option1: Circulating antibodies and antigenic cross-reactivity in Hendersonula toruloidea and Scytalidium hyalinum infections. option2: Learning the basics #4: Cryosurgical treatment of warts.

Answer:
Circulating antibodies and antigenic cross-reactivity in Hendersonula toruloidea and Scytalidium hyalinum infections.
